Profile music.

It will be a type of code you can use in your About Me, and you can have a YouTube video's audio (usually music) play when you or anyone else enters your profile. This is once again from SpongeBuddy Mania. You will have the option to turn it off if it is an annoyance.

I'll just quote myself here on a previous topic of similar nature.
 

The general thought process behind not allowing autoplay is that some people can be in public places or have other audio playing which can cause general confusion and annoyance when something randomly starts playing.
 
By just embedding the video and not making it autoplay you give your profile visitor the choice of whether or not he or she would like to listen to it.

Bottom line: Audio that auto-plays can be confusing and annoying to profile visitors. As such, it is not enabled on this site.

You could always just embed a YouTube video or Soundcloud song in your About Me section, and if the visitor wants to play the song, they can.

 

Having a song automatically play when you visit a profile sounds annoying to me (I don't like it when audio starts playing out of nowhere when I visit any site). It could also be taxing on one's internet connection. I personally don't really see any use in implementing something like that.
