@hideki no, just random songs on the radio. Just thought some of it has the "anime" sound because it's got dramatic instrumentals with melodic singing.Rap & modern pop don't try to do that, I'd rather listen to Latin stations (which there are alot of in CA). Part of the joke is that I listen to anime and video game soundtracks so much that I relate other stuff I hear to them as a metric, heh.
considering Spain's first opening it could pass as the actual one just fine, although this one is unironically good https://www.youtube.com/watch?v=YNsO3J6-7RI
