KEXP is a radio station that plays music for people who like different kinds of music. They have special DJ's (kind of like grown-up music teachers) who pick out the songs to play.
They play music from different places around the world, so you might hear a song from Japan, or Brazil, or England. They also play music from different times, so you might hear a song from the 1960s or a brand new song that just came out.
And if you want to learn more about the songs they play or the artists who make them, they have special shows like "Songbook" and "Music That Matters" where they talk about the music.
So, if you like listening to music from different places and times and want to learn more about the music, you can listen to KEXP!
