Guys, would this be creepy or mysteriously cute?

I feel really stupid for asking a cheesy guy question. Nevertheless, here I go. There's this guy I go to school with, and we're in a few activities together. During the musical I was in last year, we did Secret-Santaesque gift giving for each performance, and this guy was my "Secret Santa." He sent me a really good mix cd, which included a bunch of love-based songs. I formed a little crush on him. SO he's going away to camp, and has left his address. Would it be creepy to send an anonymous mix cd back to him, with a note saying something along the lines of "Just returning the favor [of good music]"?
