In its press release earlier this morning, T-Mobile announced that it would be adding 6 new music streaming services to the list of available providers and also gave us the low down on just how popular the latest phase of Uncarrier has been. Short version: It’s been very popular.

According to T-Mo, customers have streamed 5 million more songs per day than they did – on average – before Music Freedom was launched. In total, 7,000 terabytes of music have been streamed since it went live. An amount of music I find almost impossible to picture. Clearly then, I was wrong about Uncarrier 6.0 not being a real “Uncarrier” move when it was first launched. T-Mobile customers are clearly feeling much more free in their music streaming use now that they can use it as much as they want.

Music Freedom now allows the following services to be used on your device without it counting against your data allowance:

• iTunes Radio
• Rdio
• Pandora
• Spotify
• Grooveshark
• iHeart Radio
• Songza
• Rhapsody
• Samsung Milk
• Slacker
• AccuRadio
• Black Planet
• Radio Paradise

Like we’ve already reported, Google Play Music is going to be made available later on this year.
