Palm Centro
It looks like Pocket Tunes aka PTunes will work for you. It looks like it's included with the phone.
Here's a blurb from a Pocket Tunes "how to"... (some of this refers to the "deluxe" version which I believe is a paid upgrade)
Pocket Tunes turns your Palm device into a portable audio player! Play music, podcasts, and audio books from your collection, or subscribe to an online music service to gain access to millions of unique songs! With Pocket Tunes Deluxe, you can even listen to Internet radio anywhere that you have wireless Internet access.
Listen to Internet radio
With Pocket Tunes Deluxe, you can tune into hundreds of ShoutCast or Live365 radio stations on devices with built-in wireless connectivity.
15-2 Finding Other Internet Radio Stations
The easiest way to find and listen to Internet Radio stations not included in the catalog downloaded from the Pocket Tunes web site is to visit
Free Internet Radio - SHOUTcast Radio - Thousands of Free Online Radio Stations or
SmartPhoneTools - Your first source for Palm™ Treo™ News, Software and Accessories on your handheld's web browser. Look for a station that you want to listen to, and tap the "Tune In" button. Your handheld may ask you if you wish to Open or Save the file; pick "Open". It may also ask you if you want to accept the file; select Yes. Pocket Tunes will then load the station and start playing it within a few seconds.
After using your web browser to find a new Internet Radio station, the new station will be included in the "Unfiled" category in the Internet Radio catalog. You can use the "Move" or "Copy" options in the Internet Radio catalog's "Station" menu to include the station in another category or categories.
