Hello guys, how are you?

I am writing to you, because I just noticed that is posible for me to set the "license type" on my projects and I havent done so until now. I am a bit confused because I saw a lot of "license types", could someone guide me?

my situations is this one:

I am a composer, so I create my own music wich is already copyrighted by international laws, I am also the publisher, so I have total control over the tracks (meaning I can sell licenses to anyone I want). the thing is that I want to sell the music packs for the developers to use in their videogames, but I dont want people transform the music.

what should be the proper license for this use?

regards everyone ^^
