This brave new world has a dark side, though, and sometimes bands that aren't quite ready for primetime get launched to a brief moment of undeserved stardom before their celebrity outpaces their output. What's been lost is the idea of artist development -- labels signing young talent and working with them over time, making them pay dues with tours as opening acts, or quietly releasing an album or two before unveiling their masterpiece. Nowadays, if an artist has a hit song, they are ready to headline a tour, even if their catalog is only four or five songs deep (Oh, hi, Foster the People, we didn't see you come in). But what would have happened if blog hype had always been the gatekeeper of success? These five world-changing albums probably never would've been made.
