Depends on mood location really, The Pogues, (Favorite band) The men they couldnt hang, Irish Folk, Stiff Little Fingrs, the clash, Green Day, Blink 182, Show of hands, as well as classical music at times.
the levellers, Welsh Language bands, Y Cyrff and yr Anrhefn, Runrig, and a a good quality Welsh Choir blasting out some uplifting hymns!
Quite a mix there me reckons!
Cheers
