Asakiyume mita

Chile, long ago. Very difficult accent, spoken fast, with the mouth shut and word endings casually discarded. Bolivian is slower, Colombian and Venezuelan are fast too, but beautifully enunciated, so even a moderate speaker can understand quite easily. Mexican is a drawl, to me, and Argentinian sounds like Italian!

Chilean telenovelas in the 90s were very good. Mad, surreal comedies, not the weepy, Brazilian melodramas. If you ever get a chance to see "Oro Verde" or "Tic Tac" I recommend them highly ('Tic Tac''s soundtrack was entirely Queen songs by tribute bands, basically a homage to the music and spirit of Freddie Mercury). They have their own Wikipedia pages even!
