Google abeds copyright abuse.
Facts:
You can find almost any hit song from any decade on Google/YouTube.
There just happens to be simple plugin for Firefox that will convert Youtube videos to a sound only MP3 file.
Google music will provide you with cloud storage of your MP3s and even offers an automated backround upload service.
So with Google/Youtube effectively making the selling of hitsongs unprofitable, they drive up the prices of live concerts which have become the only way for musicians to make money now.
