Why have to choose when we can use a program with two functions in one? Agenda and radio, together in the same application with a very descriptive name: Radio-Agenda.
As you can imagine, it doesn't need much explanation. It is a program that includes a functional contact agenda, with all the fields you may need to save the information of your friends, acquaintances, etc., and also includes a search engine to quickly locate that contact you are looking for.
But in addition, this particular agenda includes a radio with different stations, both English and Argentine, to listen online while doing any other task on your computer. And this is not all, because Radio-Agenda also includes a function to save backup copies of all data in HTML format.
You can free download Radio-Agenda 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
