I'm finishing a game after 3 years and the biggest problem is when I export to Android (via monaca.io) the music loads after 10 minutes! And they are not long music...
Is there some method or third party plugin to load the audios faster?

What size is your music file? If it's a big size then try compressing it. Have you tried placing it in the sounds folder and setting pre load sounds setting to yes in the project settings
