You probably get a lot of posts like this, but I can't find any that answer my question. What is the code to insert a music url? I already have the song url that I want to play, I just don't know what tags to put it in for it to work. I've already tried to <bgsound=whatever> code, but it doesn't work. Is there a site to help me on this? Or if you know the code, that'd be great. Thanks!

For this, use the embed tag.

You take the URL of your music file, and put it in this format.
Note that myspace has some strange Java-disabling thing (or whtever it is), so autostart can't be turned off/the controls may look different.

<EMBED src="yourmusic.wav" width="125" height="40" autostart="false" loop="false" hidden="false">

You can make things true/false. The controls are self-explanatory. You can change the size too!
But as I said, some code is disabled on myspace and may not work, but the music will still be there.

Hope this was what you were looking for!
