I gave up on Bob Dylan's The Times They Are A'Changin' after about 7 tracks and never touched it again.
The entirety of Sabbath Bloody Sabbath has eluded me.
Somehow, Ok Computer has never recieved a full listen, although I have heard every track.
First time I heard Hunky Dory I didn't like it and stopped after a few tracks, now I love virtually every track on it but have somehow never listened to them all at once.
I apparentely don't have the patience for both discs of The Wall , or The Beatles in a single sitting.
