Audio that changes its music over time

I found something interesting, this Roblox audio will sometimes change its music somehow.

When I first listened to it, I thought it was a joke audio that was a copyright replacement music, which Roblox did around 2018 if an audio was copyrighted. However I came back to it after a while and it was a different song, maybe the one that was supposed to be the actual music. Then I came back to it now and it’s that same copyright replacement music.

The reviews also confirm that it plays only sometimes, and one of them said that you need to refresh a couple of times for the original music to play. Also, it seems that when you put the sound into Roblox Studio, the original song plays.

How is this done/possible? The updated date is the same as the created date, so it can’t be that.

It’s almost as if Roblox re-added copyright replacement music. Or maybe it’s just a bug.
