Where to get the names of the tracks of radio stations?

Question

PHP

Good afternoon, there is a site with popular radio stations, you need to display the names of the current tracks. But I still have not figured out how they do it, in the sense of where to get this information from. Here is an example site the-radio.ru
As far as I know, this info is sometimes contained in the streams themselves, but there are few such stations. Do they just parsyat from the office. sites this information?
In general, help is needed, I am ready to pay, maybe someone came across ...
