I think it depends on my emotionall state ~ sorry!! I know that's a girly thing to say, but generally that's the way it is for me.
When I buy a vinyl LP, I'll prepare myself to listen to the whole album; side A, then side B with a fresh coffee and the mobile phone turned off. I put more work into 'getting into' an album. Not so with CDs. Even less with internet MP3 type music.
These days, flicking through Spotify/Myspace/Itunes, I don't even listen to the whole song (some don't even let you before ramming commercials in). There were some albums that were presents to me - Rufus Wainwright for example. I listened to the album once in its entirety and took a complete dislike to his vocal operatics, bordering on hysterical pretention. Equally, inconsequential vocalists like Lori Carson - her work slowly grows on me and I find myself listening to her average voice and beautiful music more often than I'd dare admit.
Then there are new 'hyped albums', "highly anticipated", such as the Cowboys Junkies' re-recording of the Trinity Sessions. I barely coped with listening to the whole album straight through, my heart sinking closer down down to the concrete floor.
Thinking about it now, I should really prune my albums and flog off all these albums I don't listen to
