I've recommended this song a ton of times because I use it as a warm up when I play... Midnight by Joe Satriani. It's really laid back and easy... it's not balls to the walls tapping like Van Halen or Hammett.... it's what I can piano tapping. You use two hands and play the guitar the way you would a piano. One does the bass and one does the treble parts... it's not hard just listen to the song... better yet get the G3 live in Denver DVD and watch Satriani do it... then it will be easier.
I don't tap a lot so I don't know a ton of songs that have tapping in them. I mostly improvise solos anymore anyways.. Good luck with it and keep challenging yourself
