A side product of trying to do an instrumental vs instrumental mashup for this week's crumplbanger challenge - it's a mix like it's 2002 all over again! Bastard Pop rules!
Missing and Can't Get You Out of My Head are basically the same song, but from different angles, I think.
(Pretty sure this hasn't been done as there wasn't a Missing acapella in the past, but it sounds so obvious it should have been done.)
Everything But The Girl - Missing
Kylie - Can't Get You Out Of My Head
