I've started listening to full albums lately and I have to say it's a nice change of pace from just listening to playlists all the time. So far I've listened to Wu-Tang Clan's debut album, the 2004 album Nymphetamine by Cradle of Filth, the self-titled Nirvana album and American IV by Johnny Cash to name a few.

With that being said, do you have any recommendations of must-listen albums? I already plan to listen to Monotheist by Celtic Frost, several Led Zeppelin albums (at least the first ones), something by Black Sabbath, something by Pantera and something by Meshuggah (probably Koloss). Also, if you have really good music taste and have a last.fm page I'd be happy to follow that too.
