Open Windows Live Movie Maker or the video editing software of your choosing.

Add a picture to your film reel by clicking the "Add Photos and Video" option.

For instance, if uploading one of your band's songs, it would be a good idea to use a photo of your band performing.

Click on the "Add Music" tab on the task bar.

Browse for the song that you intend to upload and import it. Select the "Fit to Music" option to ensure that your video will run for the duration of the audio file that you chose.

Choose the bitrate that you feel is needed for the file, and export the video as a .wmv (Windows Media Video) file using your program's built-in encoder.

Keep in mind that the higher the quality of a file is, the longer it will take to upload to YouTube's servers.

Open your web browser and navigate to YouTube. From the home page, click on the "Upload Video" link. In the pop-up window, browse to the video that you have just created and upload it.

The uploading process will begin automatically.
