I would like to share with you this website that I found: https://emisora.org.es/
There you can listen to the radio stations with the largest audience in Spain. It’s free and easy to access and you can stay up to date with the latest news, most listened songs. You’ll be able to listen to different accents from Spain and sometimes other accents from different Spanish speaking countries. There’s even a station where they speak Catalan, if you feel like listening to some Catalan!
¡Espero que os ayude!
