It messed up FM radio too.
It messed up the retail musical instrument business too. Nobody needs to learn to play anymore. They just get recording/editing software and some other apps/tech gear and that's that.
That's one reason why Guitar Center is going out of business.
As one commenter at that site said (sarcastically, but he had a point): With Apple Loops, who needs musical instruments anyway. So much trouble to learn to play, when I can just Google/Youtube what I need to know. Music teachers are a real PITA and make you listen to boring music like Miles Davis or Bach, making me learn some stupid scales and theory. And when would I have time for Twitter and Facebook and hanging out in chatrooms. Besides, DJ's make the music **and** the money nowadays and I can just Torrent download those apps for free!
