These are amazing, Tiramisu! The Fairies Userpage looks perfect, thank you for sharing!
The problem with the music code is most likely your Dropbox link. You should first add your music file to the Public album, then right-click the file on your computer and select "Copy public link". This should be the direct link that you use for your userpage.
For example, this is the code that I'm currently using:
Code:
<EMBED SRC="https://dl.dropboxusercontent.com/u/108749630/Carol%20of%20the%20Bells.mp3" WIDTH=350 HEIGHT=70 AUTOSTART=TRUE>
The URL should look quite similar, starting as "dl.dropboxusercontent.com" and ending with "mp3".
