With the success of French in 2021, I can definitely see Belgium going French in 2022.
Probably not going to happen, but Stromae or Angèle
Belgium has carved an odd niche for them in ESC lately it seems, I think it started already a bit with Loïc back in 2015 (with 2016 being the odd man out), but intensified 2017- onwards with kinda darker "indie-Pop"-ish stuff, which I personally don't mind at all because I'm pretty much into that, although It's been a bit of hit or miss for me. I really liked Blanche's and Eliot's entries as far as songs goes (Blanche was my #1 in 2017 even, but both stagings were a bit off and you could tell none of them were ready for this yet, especially Eliot that really messed up live), wheres I wasn't a fan of Sennek's and find Hooverphonic's entry a bit "meh"... but I think maybe it's time to go a little bit lighter in 2022? (but not 2016 style!)
