I have allways liked to keep 10 some big tracks to the Final track of the set. Personaly i like to play some older tunes which usualy are much more smother / easier if you compare it to normal tracks on my set, but even still if you can't mix them (i usualy use some accappella and then launch the last "encore / big track") - last half an year i have carried these records with me (and played some of the in the end)
Mr Fingers: CAN YOU FEEL IT....Oh my gosh - it's slow as hell but it's still rocking without you need to overpitch it

CeCe Peniston: FINALLY
Robin S: SHOW ME LOVE (Stoneys rmx)
Innercity: BIG FUN
Danny Tenaglia: MUSIC IS THE ANSWER
The Crusaders: STREETLIFE (STAF's RE-EDIT) - eventhough this is "refresshed" version and unreleased it's still keep the oldshool vibe REALLY well....everybody know's this track
Stardust: MUSIC SOUNDS BETTER WITH YOU
Chigago: STREET PLAYER (better than a KD's bomb)
Martin Solveig: MEGAMIX (contains really good megamix of all Martin's big tracks) really good to give crowd some funky fatality after the set

Todd Terry: SOMETHING GOIN ON
I don't know - but i think all of these tracks will do it's trick for "classic" of the night

- Stoney u agree at all
