Show soundtracks tend to catch my attention but there are not many shows which have soundtracks that make me want to look them up and save them on my playlist. 'Life Senjou no Bokura' is one of them so am sharing links to the songs on the show.

1. Go Through, Grow Through- Ryu Matsuyama (Opening theme song)

4. Don't Turn Away- 5 Alarm (Beach scene track - one of my favourites, it's so life-empowering!)

5. Love and be Loved- Ryu Matsuyama ft.塩塚モエカ

6. Love Is Coming Home - 5 Alarm (Christmas scene track - such a cute and happy track, another favourite because it totally represents this couple to me.)

I don't know the titles and singers of the last 2 songs in the last 8 minutes of the Director's Cut so if someone can share, that would be much appreciated! 

Wow, Ryu Matsuyama did a whole album for this series? Amazing. His songs and his voice are really lovely. Thank you for sharing!

Ah, I see. Yes, I agree... the songs in the album do fit the show perfectly. Actually, almost all the song selections the production team used for the show including those by 5 Alarm, is so fitting and perfect in the places where they were used. The soundtrack really elevated the show to me.
