This single brings back reasons why people are attracted to Remioromen's music. The first track, Hotaru, is a perfect combination of classical string instruments and modern day instruments with Ryota's great voice bring them together as he has done in Kona Yuki and Island so well and reminds me alot of Island. It's the strongest track on the single and could have been a A side itself perfectly.
RUN is the second a-side on the single and lives up to the title too. It's a fast paced song with a random PV but suiting, reflecting on the fast-paced lifes people are living these ages. Works well and is a nice track
Shiawase no Katachi is the third track on the single and is no let down. Taking on a happy feeling, this track is very pleasant and is a nice ending to the single and should not be overlooked just because its a b-side
great single all round and gets 5 stars from me :)
