Spotify brought producer Quincy Jones to launch their new app featuring artist-curated playlists 
on Tuesday, but the music legend couldn’t resist dinging P. Diddy for being a music illiterate while touting the music technology.
“P. Diddy wouldn’t know a B-flat” if it hit him, said Jones in a conversation with musician Bruno Mars to mark the occasion of the app launch. “P. Diddy has a doctorate in marketing…. He’s got clothes companies and Ciroc vodka.” (Photo of Jones and Diddy with a Pussycat Doll)
The comment came after Jones responded to an audience question with an admonition to “learn your craft.”
