Nutsie is a music service launched last week lets you access your iTunes library on your cell phone.
Register at nutSie and export your iTunes library meta data to nuTsie.com. You are only exporting meta data and not music files, once you are done with it you can access all your music library from your cell phone on the go. The music is streamed from nutSie servers, so your computer doesn’t have to be running to access your library.
You can also access your library from nutSie website and share it with others. Currently nuTsie supports Nikia phones and few others.
