Since Music is streamed, preloading can't be the answer (I guess). I could put my song in the Sounds folder and preload it, but it's not the best choice. It affect performance a little bit. If I can't find a way to make Music work, I guess I'll have to do that. Thanks for the response.
I'm using WAV/ogg. The song plays fine. The only problem is that other sounds (such as shooting and hitting) don't play if the music is playing. If I disable the action that plays the music, the other sounds runs fine. In chrome no sounds plays at all, in Firefox only some sounds are played.
Maybe my post is confusing. When I say sounds, it's whatever is in Sounds folder.
That's bad to hear ): I hope this get fixed.
If anyone have a nice example of a music playing in background while other sounds plays normally, please show me! I'll put everything in the sounds folder for the time being, but I really wanted to know how to do it better.
Due to the 100 events limitations in free version, I'm going to redo my game in Construct Classic while I gather money to buy a licence. I hope Construct Classic handles sound/music more easily, since it's not HTML5.
Thanks for the attention.
