Its one thing to say his music is not for you. But why does it bother you so much? He is someone who is doing his thing, what negativity has he brought on for you to react this strongly? He gets paid to senerade chicks and make party music, come on dude.
Oh and lets not be elitist. He is an Hiphop artist, the definition of which is making Hiphop music, he is very much part of the culture (one of the biggiest promoters of it right now). And he does it consistently. There's different styles, approaches and layers to it all. He makes popular music, soft rap/rnb type of Hiphop (he is kinda is confused in what to stick with, sining rnb or just rapping). Not that sales matter in terms of quality, but he has been the at highest level of popular Hiphop/rap music for a long time now, and he got to that position by working consistently hard at making music that appeals to alot of people, if he wasnt doing consistent work he would have faded out along time ago like many do.
Two good purely lyrical rap songs with him you prolly havent heard
