I guess it depends on what you'd call 'real musicians' but, there were some very musical people on the show. I enjoyed seeing Earth Wind and Fire.. George Clinton and Outkast. That was pretty cool. Beyonce Knowles had a really cool production with the framed-thing.
I was kind of annoyed that Devon won. That song/album is his worst. Plus, the big memorial for him was a bit much. I was sad to see him go but, geez... you'd think Elvis had died.
I'm sure there was some more good talent on the show but I missed a lot at the beginning. Also, keep in mind this is only for popular music. It appears to me whoever nominates people is looking at which artists correspond with the highest ad sales for radio in the US. It's not like they're scouring the planet for new music. However, in this process, some good people do surface. Outkast being a good example.
