Well, I know at least 10 good songs that I always want to have around.
Finding near approximations to my home versions took a little longer, but here (in no particular order) you go!
Everlast - Ends
Massive Attack - I against I
Jean Elan - Where's your head at
Pink Floyd - Comfortably Numb
After Midnight Project - Take Me Home
Booker T. And The Mg's - Green Onions
Phil Collins - In The Air Tonight
M.I.A. - Paper Planes
Eddie Vedder with Nusrat Fateh Ali Khan - The long road (My version is 16:37 long)
Ng Pei Sin - Misty Heart (From my Mod collection, an XM actually)
I could easily do 100 if I had the time! Torley Wong and Madonna very nearly made the list for starters!
