Have only listened to the best rated Benidorm entries, and I didn't really like any of them besides the big favourite - which is good but not exceptional imo.
I'm not the biggest fan of the contest in general here in the 2020's - its mix of vulgarity and cheesiness is a bit too much imo. Then we have the ethnic element in some of the songs. That draws it in a quite different direction, but I've come to think that the flamenco stuff appears a bit forced.
My biggest all-time Benidorm favourite is Vicco from 2023. In 2019, I had 'La Venda' in my top 5 and was quite shocked that it didn't do well in the voting. Last year's winner was horrible, and the year before that: Well, I respect her capabilities as a singer and the fact that it wasn't pop and dance, but it was a genre entry, and I feel I need more than that.
