I never got the windows mobile app its not released yet, but I heard somewhere there is a beta one that leaked. I do have the G1 player, pretty much stoped using it. What pisses me off about slacker is some artists wont play, im not pissed pissed but a good exmaple is Bob Segar and other artists that dont want there music on digital services. I also wish slacker would promote premium radio more too. Its like grooveshark and lets you save songs on slacker. But they wont let you make playlists like grooveshark. I just want nano to make it so you can do play all and add all button to add songs. Thats good enough for me for now or cacheing.
