I am trying to make a game with music, how do I uploads it on Snap.
Welcome to Snap!, did you read the manual?
This is the category for users to provide tutorials
For Snap! users: need help with your project? Ask here!
See the answers to the similar question here, only that - instead of specifically "music" files - they ask for "sound files" in general.
I have moved this thread. I have also renamed the "How to..." category to make it unambiguous that it's for answers, not questions.
