Question about “The End” from a new Doors fan

I just listened to “The Doors” today and I thought it was a great album. But I have a question about the song “The End.” When I listened to the track on Apple Music, Morrison’s vocals sound like they’re mixed so low at the part around the climax of when he yells “fuck, fuck yea” a lot. But when I listen to the song on the official Doors YouTube page, his vocals at that part of the song are suddenly much easier to hear. Are my headphones just fucked up, or are there just different mixes of the song on Apple Music and YT? Any sort of explanation is appreciated
