3.One In A Million
All three were written/produced by Tove Lo and they all have her sound/feel to them, especially "One In A Million" which has Tove's signature "uh oh" sound.
A strong EDM track that has an explosive chorus and torwards the end of the song, Hilary samples Belinda Carlisle's "Heaven Is A Place On Earth".
This song is most likely about Mike Comrie and features a chanting chorus that will get stuck in your head.
7. Arms Around A Memory
Is a heavily produced dark and personal dance ballad.
This song was written and produced by Ed Sheeran and is a guitar driven track that highlights Hilary's vocals.
12.Night Like This ft. Kendall Schmidt
This is a more traditional duet where the singing is done back and forth by both Duff and Schmidt. This track seems to be leftover from when she was doing her more folk/pop route.
Read the entire track by track review without my shitty paraphrasing at the SOURCE!
