I would consider a fair amount of what Satch, Vai, and similar players do as "music". It's sometimes even more melodic and song-structured than the typical DT song, for example, which can be closer to fretboard exercises. And I'd put Sfogli loosely in the Satch/Vai category, it's also instrumental rock, maybe a tad proggier and more metal. I'm probably going in a different direction anyway and might use my wild card there.
