I was listening to my Youtube music radio and this song cam Happy Song - John Petrucci came up. It feels like it's made up of two songs. One is Scotty Doesn't Know. I am having a hard time pinning the other track that plays right from the beginning till 0:24. Any clue which is that other track?
John Petrucci writes original songs so I guess you mean influences? The first seconds of the song remind me of Universal Mind By Liquid Tension Experiment (also written by Petrucci)
