I'd just like to point out that Alt. is a broad term used in order to keep from the long genre/subgenre list... meaning Alt. Rock could be used to describe any rock bands sound if it isn't distinct enough to list as metal, hardcore, punk, etc.. As for my top 20 (no particular order) 1. 2Pac - Keep Ya Head Up 2. Dr. Dre - Let Me Ride 3. Nine Inch Nails - I Do Not Want This 4. Radiohead - 2+2=5 5. Smashing Pumpkins - 1979 (I know, I know...) 6. Sonic Youth - Diamond Sea 7. Sunny Day Real Estate - A Song About An Angel 8. Third Eye Blind - Deep Inside Of You 9. Lagwagon - Violins 10. Above The Law - V.S.O.P. 11. Tha Dogg Pound - Let's Play House 12. The Dove Shack - Summertime In The LBC 13. Death Cab For Cutie - Pictures In An Exhibition 14. NWA - 100 Miles And Runnin' 15. At The Drive-In - Initiation 16. AFI - either Totalimmortal, 3 1/2, Over Exposure, or Coin Return 17. The Adolescents - Kids of the Black Hole 18. Alkaline Trio - San Francisco 19. DJ Quik - Hand In Hand 20.
