I have a church that I am building and I have all these hymn audios ( Not in Developer library) and I would like to make a Gui where you select them. Also I was wondering if it was possible to only have audios on your game because I cant afford to create every audio for the 314 hymns. Thank you!
You create your own audio by paying 100R$ and uploading an ogg or mp3 with a 2 minute limit..

Other than that, is to ask users to download the audios and put them in the same location as your download folder is.. [Not allowed by Roblox, due to possible inappropriate sounds]
