NPD Group reports that music enabled phone sales, and the usage of the MP3 player functionality of these phones, is up dramatically since Q2 of last year.

Sales of music enabled cellphones has grown from 18% in the second quarter of 2006, to more than 38% in the first quarter of 2007. That's a growth rate of 111% in under a year.

Of course, simply selling an MP3-capable mobile phone means nothing if no one is using it. But that's not the case either. MP3 player functionality usage is now at an all-time high – up 82% since the second quarter of last year. In Q1 2007, about 7% of subscribers used their phones as MP3 players.

If the behavior of the market can grow this quickly in just under a year... what will it be like in 2010? Sirius/XM, are you watching this?
