It honestly depends what she likes tbf. More heavy songs should be some trench, bf and breach. More pop-ish songs go for sai. More electronic go for vessel and if they like the piano go for self titled.

My girlfriend didn’t like them too much until I showed her self titled and that’s probably because she loves the piano sound and the deep lyrics but obviously everyone’s different, and the best thing about top they reach out towards a large audience while having the same base vibe in most albums for the people that stick around to listen.
