The Beatles-When I Get Home, which ruins the flow of an otherwise perfect pop album. They recorded I Call Your Name at the same sessions. Can you imagine?
Bob Dylan-With God On Our Side. always hated this. another album where he had a bunch of better songs that didn't get used. Lay Down Your Weary Tune, for one
The Clash-Four Horsemen. bad.
The Doors-the two dippy pop songs towards the end of the first album
The Smiths-Golden Lights, pretty embarrassing
Tom Waits-Town With No Cheer (more like Song With No Melody, if you ask me)
The Who-Getting in Tune
Rolling Stones-Salt of the Earth, never bought this one
Husker Du-Hare Krsna, I mean I guess it's funny that it rips off I Want Candy, but it's terrible
goes without saying:
Husker Du-The Baby Song
Alice in Chains-Iron Gland
The Replacements-Gary's Got a Boner
Velvet Underground-European Son
also, they don't ruin the songs, but I hate the part in the middle of all those Van Halen songs where DLR just talks.
