No I kinda agree but what did you expect? High art or song that you can resonate with on a very personal level from an international competition?
Eurovision's format kinda favors low effort easy to understand songs. So rarely an artist will go there with his best song. They'll just write a pop song quite hastily specifically for the competition. It's a competition known for pop and RnB songs because they have the widest appeal. But there's the occasional outlier that also does well. We live for these moments here, like when Italy won.
If you think about it, even in Eurovision's "golden" era, the good music we remember from there is still corny pop songs like ABBA's waterloo...
Music from past looks better because it gives us nostalgy about our youth, childhod, bring back some good memories. Wouldn't say that nowadays music is bad, simply you shouldn't look at mainstream music. It applies to Eurovision too, this contest is mainly about genereic pop music. But every year we have at least we have at least few more sophisticated entries.
About Italy, seems that they simply can't send bad songs and it applies to their this year entry. And yeah, when Maneskin won few years ago, it let them to become one of the most popular bands in the world now.
You're both right, not every song from back in the day was a timeless work of art. There was a ton of corny pop back then too! Even the Beatles were written off as junk once upon a time when they first came out, yet now we see them as undisputed legends.
Nowadays there's no shortage of raw talent in music, if you're willing to dig below the mainstream hits. We just gotta put in the effort to explore different genres and find what suits our tastes - there truly is something for everyone. Same idea applies to Eurovision. Granted you'll always have some sugary throwaway tunes. But if you keep an open mind...
