According to some rumors, Apple could all digital rights management from its iTunes music store. The company is already selling DRM-Free songs from EMI catalogs and according to various reports it seems like the other three music companies, Sony, Universal Music and Warner will start selling their tunes in the same manner.

As usual, Apple stays mum about the rumors, but everybody is watching the iTunes Plus, the section of Apple’s music store where the DRM-free songs will be uploaded.

Apparently, the rumor has started from the French tech site ElectronLibre, which claimed that Apple will replace its FairPlay protected tunes with DRM-Free version.

Although, you should take this information with a grain of salt, for Apple it would be a logical choice to sell DRM-Free songs.  

In fact, as some of you might remember, last year Steve Jobs has published its already famous open letter entitled “Thoughts on music” in which he called on the four major record companies to start selling songs online without copy protection software known as digital rights management (DRM).

“Since Apple does not own or control any music itself, it must license the rights to distribute music from others, primarily the “big four” music companies: Universal, Sony BMG, Warner and EMI. These four companies control the distribution of over 70% of the world’s music. When Apple approached these companies to license their music to distribute legally over the Internet, they were extremely cautious and required Apple to protect their music from being illegally copied. The solution was to create a DRM system, which envelopes each song purchased from the iTunes store in special and secret software so that it cannot be played on unauthorized devices.” wrote Jobs in his letter. Will his dream finally come true?

For the moment, Apple is the biggest music retailer in the United States, surpassing stores such as Wal-Mart and BestBuy.
