expert help needed - songs with unusual rap sections

I need to compile a list of songs with unusual rap sections - these could be raps by singers who don't usually rap, or raps inside a song which is not of a rap or hip-hop genre.

All songs need to be pretty well known (top 20 in the UK singles charts would be great).

The list I have so far is


(1) Blondie - Rapture
(2) Deee-lite - Groove is in the Heart
(3) Erasure - Take a chance on me.
(4) Band Aid 20 - Do they know it's xmas 2004
(5) Madonna - American Life
(6) Ambassadors of funk - Supermarioland

Any more to add to this list would be great....thanks!

(7) Real McCoy - Runaway

(8) Spice Girls - Wannabe
(9) New Order - World in Motion

I need at least 12 tracks, so please help!
