When I was an undergraduate, my French teacher Zoe Petropoulou pushed me to listen to 15 minutes of radio in French every day. She said that just by listening to the sounds of French, even passively while doing something else, my language skills would improve.
When I became an Arabic student, it was several years before I stumbled upon the BBC Xtra Podcast, but when I did, I applied the lesson I learned in French and began listening to the podcast regularly. Usually, I download it to my phone and listen to it when I am walking or driving somewhere. It is the easiest way to practice listening to Arabic every day.
