Actually, the one that did it for me was listening incessantly to "Song of the plains" from Adiemus 2, part fo Karl Jenkins' Adiemus project. It has a relatively complex clap pattern that solos at the beginning of the song and continues throughout it along with very complex percussion that increaingly makes itself heard in the song. As an aside, when that song is performed live, it needs 9 perscussionists just to keep up.

Anyway, since learning the clap rhythm, that's what I unconsciously drum my fingers to.
