Radio Tray

Really neat, everything needed and no waste at all. It's excelent comes with a few radios but unlike in other similar software they all work, and you can add every station you want.

Realmente fantástico, todo lo necesario y sin desperdicio alguno. Es excelente viene con unas pocas radios, pero a diferencia de otros programas similares, todas funcionan, y se pueden agregar todas las estaciones que se quiera.

Radio tray is indeed very lightweight and a single droplist with channels makes it a clean app. It doesn't buffer = there's practically no delay but if your internet speed is lower than that of the stream (what doesn't happen anymore in modern times) it chops up the signal, again not having a buffer is a surplus for ram.
Operation: You can set it to start on login in the tray, so every stations is 2 clicks away, it has a separate volume control by hovering over the tray and scrolling (like the main volume has)
