Rap music made not to sell albums, but to sell ringtones. Can be spotted by the generally stupid-as-shit nature of the song, which has a five-second repeating beat and about three lines of 'song' which is also endlessly repeated. Totally loved by fucktards that have no taste in music.
"Yo, dawg! You dig that new Soulja Boy track?"
"Fuck no, I don't listen to ringtone rap!"
