This is for 2.1(eclair) using the basic default settings
Downloading the mp3s on the laptop/desktop and transferring is not relevant since I want this basic task.
There doesn't seem to be a free player/browser(I have tried infinity browser) capable of playing mp3 (asf/ra)streaming.
I have found that the evo4g is capable of downloading mp3 urls despite the "Unsupported content type error". It does not play them directly, you have to go to the file manager or your music.
The droidx is unable to even download xx.mp3 Save link doesn't work. Gives unsupported content type
