The Happy Boombox is now available on Marketplace. You can swap out the songs with your own music in the userdata property on the boombox entity!
Get it on Marketplace: https://highfidelity.com/marketplace/items/e9da3d33-b937-4e07-bdf8-29dde581dfd1
Get the source code on GitHub: https://github.com/misslivirose/happy-boombox
I’ll be updating the readme on GitHub with more detail about how this is made, I’m working on a tutorial for building it from scratch that will be along soon.
Thank you @XaosPrincess for the inspiration in mentioning this on another thread!
