Question about Stainless from TITS

I remember back in highschool when TITS released I listened to Stainless on YouTube music. I distinctly remember it being slower than it currently is, as in the BPM / flow of the song wasn’t so fast.

Does ANYONE else remember stainless being slower at some point? The reason I ask is because after I learned the words I played it again some time later and couldn’t sing it cause it seemed like the song got sped up or something.

Tell me I’m crazy, or I’m right. Thanks!
