BUG: Can't play music on Android 4.0.4 with Firefox 68.9.0

[Louis-7]

Describe the bug
My car is using an old version of Android which is 4.0.4. I'm using Apple Music but it doesn't have a compatible version of apps that can run on Android 4.0.4, so I'd like to play the music in the browser. I installed Firefox 68.9.0 on it but I can't play any music in musi.sh.`

To Reproduce
Steps to reproduce the behavior:

1. Install Firefox 68.9.0 on Android 4.0.4. Or maybe just install Firefox 68.9.0 on any device
2. Go to musi.sh
3. Play any music and you will hear nothing

Expected behavior
musi.sh can play music

Smartphone (please complete the following information):

• Device: Android tablet
• OS: Android 4.0.4
• Browser: Firefox
• Version 68.9.0
