If the music gets tiresome, and it pretty much always does eventually no matter how good it may be, I find that playing music elsewhere (internet browser, music-playing apps, the radio, etc.) does the trick. Best part is that I can usually change it the moment I want to listen to something different.
I'm not sure if this will ever happen officially due to copyright laws. I play another game where you can alter the game's texture and audio files to make a content pack, but I have no idea if you can do that with Wizard101.
Considering that the game is almost 10 years old and I haven't seen anything of the like I'm assuming that it's impossible, otherwise someone would have done it by now.
Yep, I love the Star Wars films. I recently rewatched the original trilogy and the prequels in anticipation of The Last Jedi. I was pretty disappointed.
I know that I can play it elsewhere. I would like to know if I can change the music in the game itself.
The only mechanism to play different music in the game is to use a music player at your house. Of course you are limited to music scrolls that you have from the game. If you want to play music that isn't from the game you'll have to turn off music in the settings and play it using another program.
