Serein (song)

The song was first released as the second single off of Katatonia's tenth studio album The Fall of Hearts on 3 May 2016.

"[7] Loudwire noted the similarity to 1980's new wave music such as The Cure and The Mission, due to its "gentle strumming and a soft lead... Jonas Renkse’s soothing, multi-tracked voice... a slightly uptempo rhythm [...] uplifting and pop-inflected [...] gorgeous, understated lead work textures"[10] A number of publications noted the song as sounding less depressing than most Katatonia songs.

[10] AllMusic described the track as being "uptempo, prog pop/rocker with ringing, wrangling guitars, fat kick drums and snare, and an anthemic bridge.

Loudwire praised the song for its "gorgeous" lead guitar work and "larger focus on atmosphere and melody" than prior music from the band.

[10] MetalSucks praised the track for "melancholic melody, the vocal harmonies" and " a cool synth interlude in the middle that gave me the shivers", and concluding that it was a "solid entry into the Katatonia canon all around.
