Upload audio files just like any other file.

In the preview window you will find an audio playback dialog from which you can play, pause your file, and even add timestamped comments.
You also retain other abilities such as appending derivatives and adding values to the file’s metadata. “XMP Dynamic Media” is where you’re likely to find a song’s Artist, Album, etc.
