I just learned how to play the acoustic part of ice cream man as played by Van Halen and it's in open e tuning, that is the only song I know in open e tuning. Does anyone know any other songs that I could play in open e tuning so when I want to play something else I won't have to tune my guitar.

I personally like classic rock and metal and classical.
You can make an advenced search here on UG, where you can choose songs in different tunings.
