Does anyone know where I can listen to streaming countdown shows of Top 40 hits or any other specific genre? I don't really have time to tune into a show on radio, but I'd like to hear it on demand.

Go to hitzradio.com to see their site and countdown schedules.

Thanks Sir Will, but I'm really looking for something that's on demand. Something I can pull up at any time. While hitzradio.com technically isn't radio, I still have to tune in at a certain time to hear the show.

Ah okay, well it is Top 40 radio and more so you can use it if you like [hopefully]!
