It will be mostly music. Try to catch some words. Try to do that for a while before you look online for the lyrics. I’ve had good luck finding words on metrolyrics.com. Memorize the lyrics and sing the song to yourself.

I’ve learned the Mexican “Happy Birthday” song. It’s called “Las mañanitas.” It’s long and it doesn’t seem to make much sense, but I enjoy singing it. Every so often I get a chance to sing it with other people at a birthday celebration. The words are in the appendix.

If you can find a talk radio program where listeners call in, you’ll get good practice in listening to different voices and accents.
