i finally found the song from BBAUS7
 

Don't you hate when you hear a song on a TV show and you can't figure out what it is?

I was obsessed with this techno song they used a lot in BB AUStralia season 7 for years now, and i could never find it or even who it was, but i finally did when i was rewatching the BBAUS7 finale, they had the DJ's there and finally mentioned who it was by. BBAustralia had really good music.

It's called "junkyard" by The Potbelleez .

Oh wow I remember I wanted that song back then. Forgot all about it.
