The problem with this is w/ the exception of Baauer, all those "artists" are novelty acts that havent become shyt once the "novelty" wore off. If you want to be taken seriously and be in it for the long haul (hell for more than a couple months) then this is def not the route to go. There's always going to be a viral sensation but your 15min going end right when the next person's begins.
I agree that most viral songs/music acts are only from either people who aren't actually music acts at all, or they're music acts that are really bad and that's why they got attention in the first place
Chocolate Rain - Tay Zonday: only got popular because of his freakishly low voice and the weird movements in the video. I don't think he actually made money from the song's sales rather than from the youtube views. He keeps putting out crap songs that people only watch on youtube for free but don't buy. He's not taken seriously as an artist
Friday - Rebecca Black: only got popular because of her horrible nasally voice and the horrible song itself. For some reason, the song actually sold and even hit the charts (I guess some people will even pay money to try to be "part of" a meme while it's hot). But she wasn't able to sell any other song after that, and she's seen as a joke. She wants to be taken seriously as a singer and that will never happen unless her voice improves
Bed Intruder - only got popular because the original video was already popular. The song actually being catchy also helped. The song even hit the charts and was certified gold. But the people behind it aren't real music artists that go on tour. All they can do is keep autotuning videos for youtube views and maybe a few song downloads. And they never quite got another song nearly as big as that one
Harlem Shake - only got popular because it was an essential part of a stupid meme. Once the meme died down, the hype died down. Song hit the charts, but does anyone really care what Baauer will be releasing next? Nope, because we all know he just got lucky with that song. Nobody is anxiously awaiting to see him on tour
The only 2 viral acts I can think of that can still potentially have a real music career after their claim to fame, is OK Go and Psy (Gangham Style). OK Go is a real band that can still tour and have success; their name was put out there because of that treadmill video, and they had a wider audience and a better opportunity to build up a fan base. Psy already had a career back home before he blew up, and you can be sure he's gonna ride the K-Pop wave for a long time, especially after being the one to make K-Pop hot around the world with that song. He might not maintain interest in the U.S., but he'll still make money and have a respectable career, because he actually performs and puts on a show, and makes catchy dance music
Oh yeah, I forgot about Soulja Boy............wait, never mind.............
Point is, I just can't see most artists being able to get popular with a silly viral video, then somehow turn it into a respectable career filled with other hit songs, that became hits because people geniunely liked those other songs - and not because it's a song from a popular youtube video. I'm not saying it's impossible, but very difficult
