Random Suggestions I thought of

[Pricerocks]

the tempo changing shouldnt be logically possible. one song has the same tempo during the entire song, if it were to change it would be complicated to understand what bpm it is and would be totally useless since we have 1/16 and 1/8 grid we dont need to slow down the songs

that is absolutely not true.  I don't even know how to explain this to you.  How can you not wrap your head around the underlying pulse of a sequence changing????

in the history of music-making there were no songs that change tempo. bpm changing is just for lazy people who dont want to using the 1/16 grids

I genuinely can't tell if this is a joke
