THIS.
1)The-Dream writes the most basic, repetitive, formulaic hooks: I luv ur girl; ooh, ooh, baby, aah aah aah, ooooo, in a falsetto; umbrella ella ella eh eh; shawty is the $hi+, the s4It; the makeup bag, the makeup bag, the makeup bag, bag, bag, bag, bag, bag, bag until I think my head will explode.
2)The-Dream thinks he's more clever than he actually is. For example, on the "Up Out My Face" track on Mariah Carey's Memoirs he had felt the need to throw in stupid, run on metaphors that messed up the flow of the song, e.g. "If we were two LEGO blocks even the Harvard University Class of 2010/could't put us back together again."
3) The-BoogieMan's music videos aren't watchable. Terius Nash's overall unattractiveness automatically detracts from the quality of the video despite him wearing a hat and glasses 90% of the time.
I'm a Trey Songz fan, but he is oversaturating the market with his yodeling.
