There's a semantics issue on this thread that I feel needs to be commented on.

Asking "is there a career left in music" is akin to asking "is there a career left in sports".

There are a lot of different career paths and areas of the music business. Some of them remain viable. Some of them not so much. As I mentioned earlier in the thread, if you want to be a performing artist, there are always ways to monetize what you do. If, on the other hand, you have aspirations of being a full time professional songwriter who writes for other artists exclusively, forget it.

It really all depends on what your definition of a career "in music" is.
