Hey,

I heard a very good track played by Markus Schulz last friday.. It's a banging dark track with a female vocal that repeatedly says "oh I wanna let you go" or something like that. There are also some other vocals and a simple melody in some parts. That's all the info I can remember, maybe someone recognizes the track. Thanks.

Is it this one? The link is clickable by the way:

Mack Vibe feat. Jacqueline - I Can't Let You Go (Max Graham Remix)

nope, much darker track and less vocals.. but thanks for trying
