Vitalogy isn't overrated, the album is only reminded for those six songs, yet most of the "mainstream fans" don't give a shit about "Satan's Bed" or "Inmortality" (just watch the reaction when they are played live)
I don't think Vitalogy is a great album, but certainly is very interesting, yet, you have to be a fan to appreciate it ...that's why the album ISN'T overrated...
