I took a liking to Iron Maiden and bought 13 albums only to realise I don't really like them at all, even the songs i thought I liked.
Biffy Clyro have a good album that I can listen to over and over.
Green day - are alright as well pre-21st Century Breakdown....I don't like their latest album.
Stereophonics when I'm in the mood are good as well but I'm rarely in the mood for them

Red Hot Chilli Peppers have a album worth of good songs, it's just trrying to remember them all so I can download them
There's many individual songs by people/bands that I like but wouldn't say I like the band.
