YouTube is a great place to upload and watch videos and listen to music, but by default YouTube does not allow you to upload MP3 files.
Like always there are workarounds for every problem in this case a new service called called MP3 2 Tube will allow you to upload MP3 files to YouTube.
Using this service you can upload any MP3 files to YouTube. You can also add a background image that will be displayed while playing the video.
The service allows you to upload videos directly to your account by using Google Sub Auth API to communicate with YouTube.
MP3 2 YouTube converts the MP3 files to FLV video so that it can upload it to YouTube.
