Say you meet someone that asks for your help because they know you are strong in a fandom. They ask you to recommend them some songs since they've heard very little and know them from something else other than music and are interested in getting to know their discography more...
Choose a title track and a b-side to give them to listen to...
For Twice I would give them
Title Track: Likey
B-Side: Handle It
Bonus: (you don't have to do this): Be As One
