another decision dilemma

One of my Christmas presents was a 30 dollar iTunes gift card. The decision looms--what should I spend my Apple bucks on?

Classic rock? Worship? New country? Bluegrass?

My musical tastes run far and wide. I listen to music all the time.

Levi had me add a few songs to his ipod:
The Devil Went Down To Georgia (not the Charlie Daniels Band)
Sweet Child O' Mine (Guns & Roses)
Welcome to the Jungle (Guns & Roses)
Paint it Black (Rolling Stones)
Free Bird (Lynyrd Skynyrd)
What I've Done (Linkin Park, from the Transformers movie)

I have no idea what to buy. Man, I have issues...
