Sound — 10
It's all of Nirvana's greatest hits. If you have this album, then you should be expecting the sound to be the same as always, with the exception of "All Apologies" and "The Man Who Sold The World," both of them being from the MTV Unplugged session, and possibly "You Know You're Right," depending on the version you have heard. It's also referred to as On A Mountain, though that was an error on Grohl's part at a concert.
Lyrics — 10
Kurt Cobain is one of the greatest songwriters of all time. The lyrics at first glance look like either deep thoughts or babbling nonsense. Some look like complete trip songs (though some are I.e. Mrs. Butterworth on Sliver: Best of The Box). However, with a closer look, you can truly understand either the joy or pain (mostly pain) Kurt tried to show through his music. Just listen to "Heart-Shaped Box" and you should get it.
Overall Impression — 9
Fantastic CD. Though it is only a compilation of their bigger hits, it still keeps the traditional feel of the band. Even the flow of the album feels right, with Kurt's 1994 remastering of "You Know You're Right" opening the album with the eerie ringing and a slithering bass. There aren't any true rarities on this album, so it's just another Greatest Hits album from another great band.
