It's a Gaelic Radio Station.

Radio Two doesn't provide a translation for Gaelic speakers, so why should Radio nan Gàidheal need to do so for English speakers?

Depending on how interested I was, I would find some way of finding out what all the programmes were but, as far as I'm concerned, it's just a nice station to switch on and there's usually good music to be heard at different times of the day.

Over the years, I've tuned into many European stations just to listen to music but I never expected an English translation.
