DJ sona's ORIGINAL in-game music

So I realize this is ages late from when it changed, but did they ever announce why they changed DJ sona's in-game music a couple months after it came out? It used to be a lot longer, and far more upbeat on her blue/red forms. All 3 also sounded vastly different from how they do now (look it up if you weren't around for her original music). Also, did they even say anything when they did this? I tried searching already, but I never got any luck on finding anything talking about them changing it, whether from other players or riot themselves. I prefer the original music over the "new" revamped, music, that blueballs anyone trying to get pumped up with the blue/red forms. Also, I tried posting this in general discussion, but the option to choose that board wasn't even on the list when I tried to create this. Wat?
