YouTube User on Sum Dumb Shit!

So since when did the users on youtube become specialists on artists? Where am I comming from with this? Well Today i noticed Souljaboy released his own version of Drakes "Successful' track, (which he did good on by the way, anyway whenever Im watchin a video on youtube ill read some of the comments afterwards and as I go on i see alot of positive comments which is rare for Souljaboys Youtube account to recive so many, But then I strted to go down and see comments like "Lil Wayne wrote this" (pause) now its not just Soulja but they say that about Drake, Lil Twist, and alot of his other artists and even One of Bow Wow Many Freestyles but people dont think Wayne writes his own shit anyway so yall just talkin out the ass!! lolz, all I gotta say is Whaaaat thhheee Fuuuucckkkk?
