Rhett and Link Sheet Music

Hey, I was wondering if Rhett and Link could release sheet music to some of their songs? (Like "I am a Thoughtful Guy,", "Two Guys, 600 Pillows", "Cheese Rap")

I'd like to know because I wanted to recreate some of the songs in Minecraft using music blocks.

I don't know if this is copywrited material. If it is, then never mind I guess.
