http://www.kcrwmusic.com <-- online streams of music based programming. You may want to focus on 'Metropolis', the program by Jason Bentley. Playlists are abundant!
You can also listen to the radio live stream. Use the KCRWlive or KCRWmusic links at the top of the page.
It is an NPR station, so no commercials outside of standard radio promotion.
I prefer Metropolis, The A Track, Pop Secret and Brave New World.
You may enjoy Metropolis, and The Drop. Using the on site navigation bar, go to Music, then click on Overview and Programs. Scroll down to any music programming you want, and click on Latest Show. You can listen to the most recent broadcast of the show on demand! Feel free to peruse the playlists as well.
