I always listen to albums in order the first time through, and usually continue to after that. I'll skip tracks I don't like, but those that I do listen to will always be in numerical order. I like to listen to music almost constantly rather than in bite-sized chunks, so I'm willing to wait for my favourite track to come along rather than skipping back and forth all the time. Very occasionally I'll come home in the mood for a particular song, and I'll stick it on repeat for a while, but those day are exceptions rather than the norm.
