Okay this is my Tutorial on how to upload music, just for you Yoshi, and whoever would like to add to this thread.

First, right-click your desktop and create a new Zip folder, as shown in this screenshot.
--------------------------------------------------------------------------------------------------
Second, click and drag the selected files that you want into the Zip folder.
--------------------------------------------------------------------------------------------------
Third, go to driveway.com, and click on the "Browse" Button.
--------------------------------------------------------------------------------------------------
Then, choose the Zip folder that you wish to upload
--------------------------------------------------------------------------------------------------
Then, once you have chosen the Zip file you are uploading, Click the button shown in the screenshot above.
--------------------------------------------------------------------------------------------------
Then, this popup will come up, and show you how much the file has uploaded, wait patiently, it sometimes takes a while.
--------------------------------------------------------------------------------------------------
Finally, your file has been uploaded! Now, you have a link to the file that you are hosting, and post that here on the forums, and we can download your uploaded file.

I hope that this tutorial was helpful. If I missed a step or anything, let me know. =]
(For the record, this was a school computer that I did this on, so basically anyone can do this.)
