What I'm trying to do is create a mod that adds a new music disc to the game. When you right-click the air with this item, it will open a link to a website that will have several downloadable songs. You choose a song and the disc automaticaly becomes a music disc for that song, making it almost 100% customizable. (i think i spelled that wrong XD) Anyways, I have no clue how to do this, nor do I know if its even possible. Helping me figure this out so I can release the mod would make the experiences of adventure maps, minecraft movies, and so on WAY better. Horror maps could have creepy music, Star Wars maps could have star wars music, anything could have ANY kind of music! So I'm asking for your help. How do I do this?!??!??!?
P.S. If you have an alternative solution, please let me know. I now realize that opening a link in-game could negatively affect gameplay, so maybe it could open up a little menu with a ton of different songs on it or something, idk. I just need a way to pull this mod off.
