Which Iberian Spanish? Note that most of those people have “softened” their original accents, but yeah, I picked the first one completely on purpose. (Buenafuente is Catalan, El Sevilla is from a small village next to Seville, Sabina is from Úbeda but best known as “Madrid’s poet”, The Great Wyoming is from Saragossa, Rosana from the Canary Islands and I don’t know where Rosana’s interviewer is from)
Another one for “don’t worry about learning a specific dialect, you’ll pick one up as you go but only after years of it, and in the immortal words of a former coworker of mine ‘who the fuck cares that my English sounds Argentinian, each of us sounds like where we’re from and this is my fourth language!’”
