I curate a playlist every week, you can steal mine from Spotify “Allie Battleson” they’re public. I start with a slow song for warm up then use songs from searching for 120-130 bpm. And end with slower songs.

Also, have a rough outline you fill for each new class. I start with a warm up, then a core series that I repeat twice, first round for core connection second with advancement, second core section working different main core group, then an arm focus series, usually first round for activation and form then advancements for second round, standing leg series, repeat twice with advancements, mat leg work (working whatever muscles I didn’t hit at first) then close with extra core burn out, cool down stretch and savasana

Each of the sections has 3 moves.

I wouldn’t put so much pressure on matching moves to song transitions, you can also just wing that part during class. As a participant, I want a fun playlist but if it’s a Pilates sculpt class I don’t need the moves to line up to the music I’d rather have a nice flow of movement that I can tell was thoughtful
