music indeed has been more publicly noticed these days, because it's so much easier for something to become popular now. back then, when there was a trend of some kind, it was usually really big, but didn't last long, due to lack of widespreadness. now, if a new trend pops up, it's surely going to pop up all over the social networks on the internet now, or becoming memetic. with all of these social networks and such on the internet being able to be accessed from almost gosh darn everywhere, it's no wonder things get shared around much faster.
i wouldn't call it a bad thing that there's so much music coming out, though. gives more to choose from.
