Basically I've been asked to send a track to be mastered by someone fairly well known for a new label. It's going to be available on iTunes and what not, so I'm pretty keen.

The problem is that I've now been asked to send each individual ''track'' that makes up the whole piece of music, i.e kick, hihat, snare, each synth part, as thats what ''the man'' wants.

Is this normal? Surely an un-mastered Wav is fine? I don't want someone playing about with the levels of my music. Don't wanna sound like an ungrateful cunt but is this normal?
