Wanted - MP3/Music Store software for windows mobile

[ramiss]

After several days of searching I have been unable to find what should be a very popular item. A Windows Mobile based app that lets you download mp3s directly to your device from a major online music store.

Either I am just not typing in the right keywords or I have discovered a huge niche market.

I am willing to pay for music but I don't want to have to go home to my pc to purchase and then sync them.

Can anyone point me in the right direction?

Thanks!

Richard
