This would cover all solos, unknown instrumentals played. On song statistics it should come up as Instrumental, or maybe not come up at all, but in setlists it should come up as whatever you type following the @Instrumental.
e.g. @Instrumental[Edward Van Halen Guitar Solo] , @Instrumental[Funk Jam]
yeah I don't want "Drum solo" coming up as a song.
Some form of @Instrumental[drum] would be good.
