One of the songs in Rock Band 1 is "Wave of Multilation." on top of the other songs listed below. But this solo is near the end an extremely short an the songs not that long either hope this helps. I got this on the first shot tried the other ones was close but never did get it an they were longer than this song. If i need to add anything just leave a comment open to suggestion for other songs.
Update Another good song with an easy solo is R.E.M "Orange crush" From RB1
