I had not actually previously known about slayradio, but, as I listen to it at the moment, it sounds great!
As the Commodore 64 is a bit before my time, I have not actually heard a lot of the songs from its time, just a few of them. But its amazing how even without any other stimulus, such as a game or video, the songs which were created still stand by themselves as an entertainment as good as the actual production that they came from.
My favourite MaSu songs are the "sidology experiments", remixes of songs from C64 games, such as monty on the run (My favourite bit of the song) and bubble bobble.
Edit: Just then sidology experiment 1 started playing on the radio, and I was confused thinking I had accidently pressed play on my music application, but then I realised I didn't even have it open.
