I'm not sure if this is the process. Make a New UI. For each Level. Set Music to UI. Link it to Level. Link Level to Next Level's UI???
Hello, You can set the music in every levels UI (if you have different ui node for each level), so every time you play the level the music will change with it.
Go to the mind map. Select the UI, drop a sound file (MP3) on the scene music button. If you want music on each level within a scene. You'll have to get creative with invisible actions or something similar. BB doesn't support it natively.
