Literally!
I'm a massive Dumonde/JamX/De Leon fan and have a list of tracks that may or may not exist:

Felysha - Why You Treat Me So Bad (Dumonde Remix)
Inner Circle - Da Bomb (Dumonde Remix)
Love Inc - Be Who You Wanna Be (Dumonde Remix)
Matalex feat. Thomas D. - Hasta La Vista (Dumonde Remix)
Oopho - Talk To You (Dumonde Remix)
Poetry 'n' Potion - Romeo & Juliet (Dumonde Remix)
JMX - Town
JMX Project feat. Zyphe - La Fiesta
Ton X - H200
JMX Project - That's The Way
De Leon - Hold Me Tight
Reel To Real - Jazz It Up (Dumonde Remix)

I think most of them are pretty old - can anyone give me any information relating to these tracks (i.e. do they exist and if so, where can I get hold of them?).

Thanks all.
