I finally had enough of the Doubetwist issues I had with it suddenly playing things at random intervals, and general slow crapyness on the OSX platform, and decided to request a Google Music beta invite. Once I pulled down the Google Music App, I thought, I would just be able to stream everything form the cloud with impunity, thanks to VM's unlimited data connection.
Problem is, I think Froyo is having an issue with the fact that there are two "Music" apps on the machine. If I try playing music on GMB, it keeps going back to the same track, which it might occasionally play. If I instead use the VM-provided "Music" app, I can play stuff that was locally stored, but 2 seconds after I hit any buttons in that app, it switches to GMB, and has even started playing a second track on top of the VM Music app.
I understand that if I root the handset, I could conceivably remove the VM Music app, but I've had no luck at all rooting the handset, using every script and app I could find.
Has anyone else had this issue?
