I very much disagree with you as an Irish person that's half Latin myself. The issue isn't with sending songs from diverse genres, it's from sending songs that are bland and stale and without an identity. I personally would feel very seen as a Latin person in Ireland to have an Irish Latin...
It is true, I can confirm it as it is on the panel. I couldn't give a toss about whether an entry needs to be "vaguely Irish" or not, I care about a good song, and for me I really enjoyed this one. I personally don't even really care if the artist is Irish, but she's Irish. High quality artist...
The first part is true. Next In Line was not the replacement, they most certainly were fast-tracked. I don't know which but one of Isabella/JYellowL were the replacement, I think it may have been JYellowL?
