As long as I can remember, I've had not-quite-obsessions for songs. I'd go to whatever lengths necessary to learn the words of a song (even buying sheet music when I was older!). Then as soon as I could sing it all the way through, I'd lose interest. After a while the rteaction would wea off a bit, so most of those songs are ack on the "like to sing" list, though none on the "most wanted" list.
