[RMVX ACE] HELP WITH MP3 MUSIC FILE

Hello everyone. Spirit here. While I was making the new update to Dragon Ascension I noticed that I didn't have a final boss track. (I like to plan ahead) I downloaded a song from the game "Kirby Triple Deluxe" into my game from a reliable source. I tried playing it in sound test but it didn't play. I tried it on a battle test but it wouldn't play. I restarted VX Ace and tried playing it again, you guessed it, it didn't play. So then I looked in the BGM folder of my game and I saw that the music file that I just downloaded was 9411 kilobytes. I have another song downloaded that is 9347 kilobytes and it works fine. Is there a kilobyte limit on VX Ace on how much data a song can hold? Thanks and bye.
