The code to do back to back music
In the <head> of your page
<meta http-equiv="refresh"
content="6;url=http://your_second_music_here">
Then in the <body> of your page, put the first song
as usual. It is best to use a short one here as you will
need to time how long it takes and then put it in the meta
tag, where I have 6. This is the number of seconds you
want it to wait before playing the second
song.
