My friend is using my music to play at events

So my friend recently started djing after seeing me do it for a while. He has better connections than me and so has been offered to play at a few events by some managers etc. the only thing is, he wants to take MY laptop and usb with all the music I’ve taken hours to prepare? AITA here for saying absolutely not as that basically ruins the whole point of being a unique DJ and basically being lazy ?

EDIT*** There is one or two I can possibly dj at ALSO….. but he still wants to play either before or after with my entire music library.. so I think the best option here is to tell him to make his own libray (which he is more than capable of doing as he has done before)
