RadioSure is a piece of software that enables you to listen to internet radio. 
There are already over 12000 radio stations installed, and the list is continously growing as new radio stations become available. You can quickly search through the list of stations for your favourite station, or you can search for stations from wherever, that plays your kind of music. RadioSure supports the most commonly used formats like MP3, wma, ogg vorbis and aac+, and you can even record from the radiostations and save it as one or more sound files on your hard drive.
RadioSure is available in two versions, one regular one that you install on your system, and one portable version. The portable version is not installed, you just unzip the files wherever you want them, and start the program by doubleclicking on the exe-file. The advantage of the portable version is that you can put it on a external drive or memorystick, and it doesn't alter your system in any way. If you are a user of LiberKey, you can also add RadioSure here, you find it under "Audio > Radio".
