Some new iPhone music apps of interest...
iMeem has an app out that has similar artist playlist functionality as last.fm and pandora.... the feature that being touted is that you can upload music to it's site and then stream it your phone anywhere. however i wouldn't personally put a great deal of effort into uploading music to the site, as money and licensing woes abound for this site. plus, when transferring my uploads that were on anywhere.fm to iMeem all them have disappeared. it would appear that unless a track already exists in their database it wont upload. hopefully 8tracks.com will have an iPhone app some day, I like that site mucho more than iMeem.
Depeche Mode - Sounds of the Universe app allows one to great mini remixes using several song loop snippets. Had some fun creating glitchy remixes...
Junior Boys - Has full length songs and videos for stream, news, tour dates... all in all a pretty slick app
Kitsune Maison - an electro music label out of Paris has a new app out with streaming 30 sec samples from their future and current releases.
Haven't spent much time with the Rentals app which chronicles their year long project "Songs About Time"
