There’s yet another option for you to get mobile music. Mercora M lets you use your wireless device to stream the music you have stored on your computer.
If you are bored of your own music you can also choose from thousands of internet radio channels, or you will eventually be able to listen to music from other Mercora users. The service only works on Windows Mobile 5.0 devices right now. And is free until October 31, then $4.99 a month or $49.99 a year. Sounds good, as long as your wireless service is good enough to not hiccup your beats.
