In short:
Armenia - Generic and utterly forgettable. At least the dancers were good.
Australia - Time to check whatsapp
Austria - Discount popified(er) Jason Mraz
Azerbaijan - Wannabe 2014 Miley Cyrus / pseudo-trapper with a shitty song
Belarus - Lumineers Kids Edition
Belgium - B-team Adele with a rejected filler song remixed by some Zedd wannabe
Bulgaria - Is that La Roux? Nvm it's some boy with a generic dubstep-lite spiced ballad
Croatia - Credits song for Disney's Hercules 4: Pain and Panic's Periplus. Lol gimmick
Cyprus - We're only going to get the guaranteed 12 from Greece so who cares
Denmark - Rejected MGS song
France - Literally can't remember anything other than a pretty girl
Germany - You won't BELIEVE how these composers tricked DAVID GUETTA'S lawyers
Greece - Am I distracting you from my horrible voice with my beautiful face?
Hungary - I guess someone had to fill Turkey's role somehow
Israel - Legit went to pee after the first 10 seconds so can't comment. Probably bad tho
Italy - Mediocre song with a boring gimmick and cheap "woke" social message
Moldova - "Guys look! It's the leg song hah" was probably their miserably failed goal
Netherlands - Buy the DTV Prince of Egypt 2 movie and get the track for free!
Norway - All the trendy instruments and sounds couldn't save our trash song so... faces!
Poland - Winner of the 2016's James Bond Con of Gdansk fan song contest
Romania - Heidi (2017), the shitty live action reboot nobody asked for. Hot guy tho
Sweden - Uncharismatic Justin Timberlake with your usual swedish "I WANNA WIN" trash
Ukraine - Somewhat decent Billy Talent Zero, still too many calories for Eurovision
And now for the two deserving of more lines.
Portugal - Insufferable pretentious douchebag singing a terrible song that is so boring it could put a fucking 860400kg whale to sleep. Slow pace and little production isn't equal to good song and your song is, in fact, trash
Spain - Hahahahaha. That's a good summary on its own but anyways: laughable wannabe surfer daddy's boy kiddo with below-zero stage presence or experience, awful presentation, annoying "dancers", pathetic Disney Channel third-division-Bieber-döppelganger-show's theme song. In short: absolutely embarrassing garbage.
4/10 one of the worst editions in ages, which is saying a lot because the show is generally trash. An absolute pain to get through.
