In my city, Boosie is a god. Literally. Like 18 year old kids know his work from '02 word for word. He's definitely a trap artist.
I consider Wayne circa 02-05 a trap artist too. He had the first Gangsta Grillz...
To me Boosie falls into the category of down south gangsta rap (which is different from Trap music). I don't know about the younger generation (18 & younger), but my generation grew up on Boosie and we still love him/Webbie for the music they put out. Really wish him & Gotti would get back to pushing their music heavy.
That "Free Boosie" ish was just a trend. Most of those people that were saying that didn't say ish the day he was set free. I went & bought his newer project when it first released off his name alone.
