Well, I guess my taste has changed... most of the "club" songs are too generic for my taste; don't mean to be disrespectful, they're ok to dance, but not what in my opinion would call a great song. Any AI could replace the singers in most of those entries and sound better. I guess that's what happens when you replace actual instruments and voices for computers and Autotune
However, there were some songs I actually enjoyed, either because of the vocals, the lyrics or the interpretation; these are (in no particular order): Bulgaria, France, Poland, Czech Republic, Denmark, Azerbaijan and Belarus, and contrary to most users in the forum, I just loved the Portuguese song
