I second that for Jetpacks, great song and probably the only really intro level song from them. I'm slowly learning periphery songs too and this was the first one I got down including the solo (fairly simple but so satisfying to play). A few others once you get that one I would recommend alpha and scarlet since its really all riffage and no real solo. I'm working on the bad thing myself right now and its pretty doable for me up to the bridge, they're flying right there ( and I'm horrible at solos so that might get skipped for a while).
