Aside from there being different judges in both lists, the Rolling stone's 500 list takes cultural impact into account along side the quality of the song, where as the Dylan list only looks at the quality. I don't agree with every song on this list but overall its a good ranking imo
It is not a terrible list it seems interesting I loved to hear songs from the following list it all about taste we can't say anything to anyone but I really appreciate your work . Spell for love return
