They got their fame from Purevolume.com and Myspace.com
Really guys, it's not about what genre they are. Whether they're emo/punk/rock/alternative, whatever.
The point is, it's good music.
Boys Like Girls is my favorite band
They are a self-proclaimed emo band, which is exactly on the mark. People often mistake punk and emo. BLG knows they're not punk. They get influence from punk music..but that's about it.
The band was really good when it was underground and stilll fresh back in 2006, but they're getting bigger and starting to sell out. They're crowds have become largely scene.
