I borrowed my FI's iPod for work today because I'm too lazy to update mine and his has more music. He has varied music tastes, so not a lot of the stuff on there really raises an eyebrow for me, and some of the stuff is on there because I asked him to put it on (like Florence + the Machine).
I was flipping through tracks and...Katy Perry came on!? I had no idea he even liked Katy Perry's music and, even though I do, I didn't ask him to put it on there! Teehee...
What's the weirdest or most out-of-the-blue music you've found on your SO's iPod?
