There's "musical and non-musical" examples to be found in any aspect of musicmaking.

Musical and non-musical drum solos.
Musical and non-musical (pick any instrument) solos.
Musical and non-musical compositions.
Musical and non-musical musicals.

Even "less is more" (oh, how I hate that phrase) drumming can be unmusical, if it's not what the music calls for.

That having been said, it's cool not to be a fan of drum solos, and it's cool to be a fan of drum solos.
