... as a warm up for practice?

While sitting in front of the TV?

I was goofing around on the gitfiddle yesterday, just playing some scale patterns and noodling.

I noticed what I was playing sounded familiar. Rearranged the fingers a bit... and it was Funk #49! Pulled up YouTube, and was jamming along within 10 minutes. It was a blast to play.

So, are there any songs you've "accidently" fell into learning?

Are there any songs that are just a joy for you to play, no matter how many times you play 'em?
