I have listened to this album so much when it came out - it's difficult to give an objective opinion on it (but since when do we need rationality in music). It's a 5 for me... I love it, and its legacy is huge (not just because Kurt Cobain died a tragic death). I see youngsters with Nirvana T-shirts on an almost daily basis. Nirvana originals have been completely reworked, I think we weren't expecting a grunge band to do this at the time. Add a few fantastic covers (Bowie, Leadbelly etc.) and you have a stonker of an album. A true classic.
