No, you interpreted it correctly. I don't think rappers are in any way, shape or form musicians. They're entertainers, not my cup of tea but entertainers none the less.
It was your other comments about long hair, needs a bath, etc. that harken back to what the older generation might have said back in the 60's and early 70's about rock bands and hippies that I don't see being applicable today. Anyway, I don't want to screw up another fun thread, so I'll end by saying I respect your personal view of that genre. Plenty of room for everyone.
