I don't know man I feel like the biggest loser in the world when I tell people what I like. (Not that I care...) I tell people and I get the whole O_O look or the awkward, "Ooohhh''. Sometimes people even have the nerve to say they listen to it all the time and clearly don't. I definitely agree with Kop on what he said earlier. I think to a degree it is trendy for car comercials and stuff like that...and there are some bands that definitely improperly label themselves as Garage or whatever. I don't know why that is, but then again some people call Metal Rock 'n' Roll and I definitely couldn't agree less.
On a side note: I do think it could go big in a real and honest way. I think this because there are a ton of people who can't stand rap or techno..and that's all you have a choice to dance to these days. I find that pure Rock 'n Roll is quite dancable and could make a huge comeback if done by the right bands, with the right DJ's, and the right people starting it.
