When I wrote about music players for Android, I mentioned my struggles with getting Jinzora to stream my home library to my G1 by turning my primary Linux box into a LAMP server. The server is up and running, but I can't get Jinzora to download the music. I haven't taken my new Mac for a spin down this road yet, so maybe that's next week's project.
Until then, I can upload audio, video, and image files to imeem's server and painlessly stream them to my G1 from there. The old imeem software has been replaced in the Android Market by the new imeem Mobile, and it provides a new tab for My Music. Along with the announcement of this software, which was sent to the imeem mailing list I belong to, was a link for getting the standalone uploader. You can accomplish the same tasks through the website as well.
The uploader works with Windows, Mac, and Linux. (Much appreciation for playing nice with everyone, imeem.) It does require Adobe Air 1.5, though - which isn't easy to accomplish under the 64-bit Linux on my laptop. So I went for the Mac version, as you can see in the screen-grab below. The uploads worked fine, and my streams were almost instantly available.
Check out a somewhat informative and highly entertaining spot featuring a band called We are Scientists talking about the new program. When you're done with that, snag the free software in the Market, and get the beta uploader for your computer. You've got to log in to download.
I ran the app and chose to upload from iTunes, rather than browsing files in the finder. So the "null" marks below indicate that I haven't labeled, tagged, or categorized those songs. It is a new computer. You may also see the blurb that says DRM-addled tracks from iTunes won't work - in case you have a few thousand of those laying around. Of course you could always remove the DRM from the entire batch with a couple of clicks or replace those songs with good files via BitTorrent.
