- heart shaker
people say it's bubblegum pop, but it's done better than every bubblegum pop out there. there's half time, real snare sound, quite daring chord progression, from the first listen you'd know that this is quite the high budget song
- like ooh aah
dance break, half time, chord progression of I-IV seems generic but they did great layering and sound design so it doesn't sound very common
- fancy
simply the best pre-chorus in the history of kpop. great bass line, nicely textured rhythm section, i have my gripes with this song like how the chorus somehow have less intensity than the pre-chorus/verse, but each compose their own i guess
- pony tail
i'm a fan of rock 
- dance the night away
nice uncommon rhythm section, very catchy leitmotif
