Apple Inc. (NASDAQ:AAPL) is in negotiations with major music companies to give customers easier access to the music that they have purchased across multiple devices. Apple is negotiating with Universal Music Group, Sony Music Entertainment, Warner Music Group, and EMI Group.
What this means is that if you lose the purchased music files from iTunes through your MacBook, you can download them again for free on your iPad. Apple became the largest U.S. music retailer in 2008, beating Wal-Mart.
Personally I think offering the ability to sync your music across multiple devices would be a good thing for the industry. If people knew that you can download music again that you purchased, then they would be encouraged to pay for more music instead of stealing it.
