Aren't ALL drummers musical?Definitely not. As a drummer for nearly 30 years, I'd say there are very few who qualify as such. A musical drummer plays compositionally, carrying a tune of their own, even when playing solo. Not many, even the phenomenal drummers in the top-100 list, are capable of being more than timekeepers and technicians.
For musicality, you can begin with anyone who ever played for Zappa...Bozzio, Wackerman, Colaiuta.

Mark Brzezicki
Oh yeah, Dennis Chambers. Let's not forget him. :-)
