What this will change probably isn't pop music, it's soundtracks for TV commercials, video games, shows, movies etc.

Currently to put music in something you need to license it somehow, in most cases the generic music you hear in most media is sourced from a company that has a library of royalty free songs that they sell for a pretty hefty license fee.

Imagine being able to instead go into some software and punch in some keywords to describe the scene, the duration, track what happens in the scene on a timeline of some sort and let the computer render original music for the score. No middle men, no musicians, no royalties or licenses other than for the software. It would change the industry overnight.. and make being a professional musician even less promising of a career choice than it is today...
