About damn time.
This is another move to protect the current delivery system (hard media like CDs). There are legitimate uses for file sharing.
1. To share files. Not all files are music files.
2. Most musicians make $0 from their album sales (has been true for a long time. They make money from live shows. There is a growing movement in the music business for bands to totally bypass the record companies. They are producing the songs themselves, and putting the songs up on file sharing sites. This is the real target of this move, as it will eventually put an end to record companies.
I support the record companies from one standpoint. They own the copyright on the music they sell, and only they have the right to sell it (or give it away via file sharing.)
However, that right extends to everyone that produces music. If I form an independent band, record songs on my own, and want to give away copies of my songs via file sharing to promote my band, that is also my right.
The fact that someone is sharing an mp3 file DOES NOT mean they are sharing it illegally. The record companies are trying to shut down their biggest future competitor: independent artists that CHOOSE to give away their music via mp3 & file sharing.
