Hard to articulate any better than that.

There are a great, great many songs that I don't like; and a smaller, but still large, number of songs that I like, and steal with gusto, vigor, and no shame at all. (Actually, I do pay royalties when I record them, but I only record a few). There are also some songs that I do like, but that still aren't my kind of song as far as singing them myself. I'm not sure what the criterion is. Part of it is that I like a fairly strong rhythm, and that song is more freeform. But there's more to it than that, but I'm not sure what it is.
