Do it yourself music.

The is very well written:

Because of streaming and downloading--both legal and illegal--the music industry is changing in fundamental ways. This is why Google purchased music licensing firm RightsFlow for integration into YouTube and how venerable music mag Spin ended up getting purchased by blogging outfit Buzzmedia. In the end, in order for music industry firms to thrive, they're forced to try entirely new business models, and nimble, tenacious, DIY-driven outfits like Songs are just better equipped for mosh pit-style business than the suits at the majors.

With blogs, YouTube, twitter, and online stores, musicians can now DIY everything.
