Even though I consider Radiohead to be one of my absolute favorite bands ever, and have like 2,4k plays with them on lastfm - I still haven't heard Pablo Honey.
I'm not really sure why I haven't spinned it yet, but I guess it's mostly because I rank The Bends and OK Computer as my 'least' favorite albums by the band, and if Pablo Honey sounds similar to The Bends, then it doesn't feel very interesting.
Obviously I've heard Creep, but not really a big fan of the song, and if the rest of the album is like that, then meh.
I'll most likely check it out though, I'm planning to do a "check out albums I dont know by artists I love" this year, there are more examples like Thrice (only heard the latest 4 releases), Dream Theater (haven't heard WDADU in full yet) etc etc.
