It is fairly self-explanatory, but just in case - instructions on how to use the dropbox:

Select (click on) your concert folder, then select (click on) the song you want to hear. After clicking the Download button in Dropbox:

• In Internet Explorer you will get a message to Open or Save.  If you click Open, the file will be downloaded to a temporary directory and they played on whatever your default music player is.  If you click Save it will save to your downloads directory and then you can play it or move it from there.

• In Chrome, the download will start immediately to you default downloads directory.  If you click the button representing the downloading item, it will set it to open when the download completes.  You could also use the pulldown on the object and set the option to Always Open This File Type after download; that would set it to run after download.
