I know some people want to get songs up, but due to lack of technology, they can't. I have actually figured out a way to get a song up. All you need is a type of usb microphone. I use a logitech eyetoy usb camera, but it has a built in mic.
1.Create an account on ustream.tv. Start a broadcast and then make sure that it is set up correctly (take off video broadcast). Click the start record button and start playing whatever you want.
2.Now whenever you finish playing your song, save the video. the go to the my videos tab and you should see your video. If you scroll down, you should see a .flv. It lets you download the file, but as a flash video. Don't worry if your computer can't play it, because it doesn't need to.
3.When you download that file to your computer, go to
http://media-convert.com/. Browse for your file, then scroll down and change the output to an mp3 file. It will convert it and bring you to a page where you can download the mp3 file.
Bam!!! Now you have an mp3. Any questions?
