I'd love to have this. The Pandora app shows the Pre's potential for online radio and background apps. There's tons of other online radio apps now available through the official catalog and homebrew, only Last.FM is lagging behind!
it could scrobble from the palm integrated music player (or the even better remix one) and integrate the friends in synergy (shouts from the palm messagin app?). Palm offers a way for two cool features besides the "normal playing"...
I really hope that last.fm gets on the band wagon and develops an APP in the fall when the revamped WebOS comes out!! Now that HP has the money to push WebOS for the PRE and Tablets... I am excited to see what apps come out.
Unfortunately we aren't, we don't have enough resources to focus on too many mobile apps, apart from the iphone/android official apps. However, we do encourage devs to make their own apps using our api, and offer support to them via our forums.
@Last.fm Employs. I don't know if you haven't herd but HP bought palm and webos platform. There already making new devices for webos. It will inevitably be a big platform soon. You should consider making an app now rather then later.
