Most of these records are on vinyl, bought a long time ago. It was the golden age when I went to every record fair in town.

i'm a bit stunned because it's Captain Beefheart (12 albums) and he's not by far one of my most favourite artists. so if it's up to the sheer number of albums by an artist that i do not only own but REALLY appreciate, it's definitely The Beach Boys (6 from 10), Mercury Rev (5/6), The Fall (5/9), Tom Waits/XTC (both 5/11), Scott Walker (4/6), SFA (4/7), The Flaming Lips/Robert Wyatt (both 4/8), The Kinks (4/9) and Elvis Costello (4/10). yet proportionately to the amount of long play releases, the award ultimately goes to The Zombies and My Bloody Valentine by a hit ratio of 100% due to their respective two superb studio albums and to The United States Of America, bearing their first and only (self titled) record in mind.

awww. nowhere near as many albums as most people.

I need a few questions answered first before I can participate. Do remastered, bolstered up editions of albums count separately? What about remix albums? Live albums?

i personally excluded all remastered, remixed and compilated versions. just as if i'd consider "star wars" and "episode IV - a new hope" to be the same. well, from my POV. since dumbangel's suggestion included compilations - i guess you can summon live albums as well. further, studio albums should only be named once (no matter, if remastered, ‘82-esque or vinyl..), singles and ep's are strictly forbidden (whooo, right NOW i feel like i'm one of those participants of the ministry of truth)...

Moonbeam, of course you can include remix albums and live albums.
Let's all play a little funny game : To guess how many Prince (or Love Symbol or The Artist or whatever you want) records Moonbeam own ?
I would say...57 records

Henrik, what a huge collection you own ! I'm very impressed !

Dumbangel, the answer to the Prince question depends entirely on the inclusion or exclusion of bootlegs.

Here's the list of artists of whom I own at least 5 official albums. For the record, let me note that I feel this scheme distorts my tastes, as a lot of artists I adore haven't released a great deal of records. I'm sure you will get quite a well-deserved laugh at my expense for some of the selections!

Prince- 40 (as if you all couldn't guess)

David Bowie- 23 (not my 2nd favorite artist, but he just has so much great stuff)
The Cure- 20 (my favorite band)
Kylie Minogue- 20 (hell yeah, bitches!)

Madonna- 19 (JR isn't the only one pimping Madonna)
Blondie- 17 (they have more compilations than studio albums!)
Lou Reed- 15 (I haven't listened to a number of them yet)

New Order- 14 (18 if you count Joy Division)
Depeche Mode- 13 (How the hell am I missing A Broken Frame?)
Eurythmics- 13 (my favorite group- I've get well over 100 if you count singles/bootlegs/etc.)
Björk- 11 (I even care enough to include the umlat)
Janet Jackson- 10 (soon to be 11)
Roxy Music- 10 (better late than never!)

Human League- 9 (probably more than I should)
Stevie Wonder- 9 (definitely less than I should)
Grace Jones- 8 (If I can ever track down Warm Leatherette, I'll happily make this 9)
The Doors- 7 (doesn't everyone?)
Echo and the Bunnymen- 7 (seems enough)
Roxette- 7 (OK, I like Roxette. There, I said it!)
The Smiths- 7 (If only they had more...)
Velvet Underground- 7 (Them too...)
Aerosmith- 6 (Don't front- Pump is the shit!)
Busta Rhymes- 6 (my favorite rapper)
Micheal Jackson- 6 (my favorite headcase)
Missy Elliott- 6 (my favorite female rapper)
Morrissey- 6 (I'm sure he rues the fact I don't have more)
U2- 6 (I can't seem to love them as much as others)
Aaliyah- 5 (RIP Baby Girl)
INXS- 5 (I'm sort of over them, but I'm still glad to own them)
Joan Jett- 5 (I wish I had more)
Kraftwerk- 5 (I'm looking to expand beyond the magical Autobahn-Computer World run)
Parliament- 5 (8 if you count Funkadelic in there)

I would have been able to tell you the two first by memory, but had to go home to check who came in third:

several dozen: Bob Dylan
19: Bruce Cockburn (Canadian singer-songwriter, strangely unacclaimed)
13: Warren Zevon
12: Beatles
10: Lou Reed
9: Patti Smith
8: Nick Cave, Aviv Geffen (Israeli singer); Richard/Linda Thompson; Steve Wynn
7: Gasolin’ (Danish 70’es band); John Hiatt; Pink Floyd; Rolling Stones
6: David Bowie, Byrds, P.J. Harvey, R.E.M., Neil Young

I’m afraid this shows me up as a conservative geezer, mostly :-)

Actually, there are 8 Earth, Wind and Fire-LP’s standing about on the shelf as well, but they’re my beloved girlfriend’s property. Technically, she’s responsible for the pre-Revolver Beatles stuff as well, but those I do listen to, so I’ve included them :-)

(Guess I ought to give EW&F a listen too, seeing that they're there)

I counted only LPs and CDs. My sizable collection of cassette tape copies of friends’ LPs (amassed while an impecunious student) could push Reed and Young up a bit, I guess, but most of those have found their way into the collection as ”real” albums later. Come to think of it, though, there are some that I would pay through the nose to get, but can’t find, and if included, they would push John Cale from his present 4 to 7 or 8.

22: Bob Dylan
15: Neil Young
14: David Bowie
13: REM
10: Beatles, Sonic Youth
9: Ryan Adams, Elvis Costello, Super Furry Animals
8: Rolling Stones, Bruce Springsteen, Tom Waits
7: Blur, Nick Cave, Oasis, U2

Plus heaps more on 4,5&6.

dumbangel, you started the flattering, so i'd like to join in: he recently noticed your 9 bjm, 6 boo radleys, 5 broadcast albums - great accumulations, netjade stands in awe. big ups.

Bob Dylan 44.

13 : REM
9 : Tindersticks, Alain Bashung (French singer)
8 : Swell
7 : John Coltrane, Rolling Stones, Pink Floyd, U2, Tarwater (German band)
6 : Miles Davis, Beatles, Smiths, Radiohead, Pavement, Tricky, Pere Ubu, Nick Cave, Miossec (French singer)
5 : Velvet Underground, David Bowie, Talking Heads, Beck, Eels, XTC, Bjork, Elliott Smith, Tetes Raides (French band)

Bob Dylan 44.

This beats Moonbeam's Prince collection!!!

Well, if I was able to count singles, special editions, bootlegs and the like, I'd be over 200 for Prince!

I didn't know that Kylie Minogue had made so much albums (20). I would had thougt she had made no more than 7 or 8 records.

Kylie has more compilations than she does studio albums! And I'm a sucker for them. Granted, Let's Get to It is by far the worst album I've ever heard, but by golly, I love that lass!

The Beatles 10 (11 if you include a John Lennon Record)

Well, I'm afraid I'm not quite original, but here I go:
- 23 albums: Bob Dylan.
- 17 albums: The Beatles.
- 11 albums: David Bowie.
- 9 albums: The Rolling Stones.
- 7 albums: Radiohead, King Crimson.
- 6 albums: The Beach Boys, Elvis Presley.
- 5 albums: a lot, including among others Prince, Bruce Springsteen, The Smiths, The Pixies, Björk, R.E.M., Bob Marley & The Wailers, Elvis Costello, Paul McCartney and Lou Reed.

But the absolute record of a single artist collection undoubtedly belongs to my friend MyGent, that owns 41 CDs, 17 vinyls and 3 EPs (and many videos and DVDs) of David Bowie.

10 Records
Metallica

9 Records
Pearl Jam

8 Records

I'm surprised Beach Boys weren't the tops for Dumbangel:

Beach Boys are mine. Every single studio album, plus about 4 live ones and 3 or 4 boots and both the Pet Sounds box and the Good Vibrations box. If you include solo stuff I have all Brian's albums but 2, Dennis' only 1, Bruce's CD, and *blush* Mike's album (I'm a completist..)

Beatles after that (unless you add in solo stuff and then they might tie or exceed the Beach Boys..at work so I can't count exact #)

a bunch of Cake albums

Petra

Johnny Cash

and possibly DeGarmo and Key in at the end..
