Because pro tools is awesome!? Marketing and "the next big thing" mentality I'm afraid. It sells - like the cheeky girls did. Put an average population in front of real genius music, like Handel or Bach and they will either get bored, call it whatever defamatory that comes to mind or say "wasn't this a commercial?", or in the minority I would imagine be inspired by it and class it as something great. Put them in front of something mindless and catchy, like any random bubblegum dance music and they will like it in general, they do not need to think. I guess people generally are lazy when it comes to music, its just something that hooks you in rather than something to analyze.
