Great music!


I live in an area of Contra Costa county that for some reason doesn't get the 91.1 station anymore. It came in clear up until a few months ago. So, this app and the website are the only ways to hear the amazing music played over the radio waves.

I agree with those below, that the only strange glitch with the app is when I press Pause, a couple seconds later it switches back to Play again. It is embarrassing when I accidentally open the app in public and music blasts out from my phone with no way to actually pause it. The only way to stop the music is to close the app completely. And yes that has happened more than once...

Otherwise, I love the music that KCSM plays--and since I can't get it on the radio anymore, the app is a window into that musical universe.

Still ugly app and a giant step backwards.


UPDATE: 31 Dec 2014
The latest version of this app is still ugly, though not quite as bad as the last one.

It's buggier, too. When streaming, I can't open the menu or select the i icon. There's still no in-app volume control. Every player app I've used has one, a big convenience when using an iDevice one-handed.

The original app was well done and a thing of great beauty. This one needs to be razed and replaced.

What happened to the elegant KCSM app?!

This app is seriously ugly on it's own merit. And compared to the original app, it's a nightmare.

There is no playlist. There is no volume control. And it's ugly. The On-Demand feature is so limited it has little to no value. When the phone locks, there's just a black screen with the phone's volume control showing. There's no visual indication you're listening to KCSM. This is low-bid work.

And you've killed the previous versions forcing an upgrade. A very Corporate move, KCSM. Why did you do this?

To summarize:

New layout - UGLY
New Features - MEH
User Friendly Interface - KLUDGEY and LACKING
Removed Useful Features - ACCOMPLISHED

You need to get your money back from the developer. I've deleted it and will not recommend it.

Apps don't get better than this...


KCSM obviously has the resources to get top app-writing talent since they are owned by the College of San Mateo (CSM). Their efforts shine in this app making it is one of the best of apps of any genre.

Solid. Fast. Reliable. Works great with my LG Bluetooth stereo earbuds. Another great feature is the Playlist detailing artist, title, album. Note however that very late night emcee Bob Parlocha skips the playlist entries but more than makes up for it with his commentary on the artist plus whoever is playing what. His knowledge is vast. His delivery is without grandstanding...just the information punctuated with great personal story
