In a press release, Angèle stated the meaning behind the song: "Bruxelles je t'aime" was composed during the first [COVID-19] lockdown.

[5] Focus on Belgium wrote that the song is "set against the background of a message of political appeasement between the north and the south" and "describes all the love she has for her city".

Zangba Thomson of Bongmines Entertainment commented that "Bruxelles je t'aime" has "a relatable narrative, ear-pleasing French vocals, and tuneful melodies.

The likable dance-friendly tune possesses lush instrumentation flavored with an awesome French pop vibration".

[7] An accompanying music video was released on 21 October 2021 and depicts Angèle dancing and celebrating on a train from Paris to her birthplace, Brussels.
