Though most musicians would look at drum or percussion music and lose their minds. If you're talking percussion (not counting marimba and other keyboard-like instruments) the notes will generally be all on one line. Or rather each line is a completely different instrument. Often each instrument will have a different-shaped note head.
Then there's the stuff they give the guy playing the drum set in a pop/jazz/rock etc. band. It's frequently so over-written it's nearly unplayable. I usually just asked for the lead sheet (for standards, the kind with a melody and chord progression) or a copy of the first trumpet part. Basically give me the melody line and let me figure out what to do with it.
