C60, C90, C120 - terminology from many years ago which if you were born after 1985 you probably have no idea what these mean.. Read the detail on Wikipedia.
Well for the older Metallica fans, they've announced they are releasing one of their 1982 songs "No Life Til Leather" on cassette in summer 2015. Luckily they will also release it on CD and LP too at the same time for those who haven't got a cassette player to play it on. Thinking about it, I wonder how many people still have one hanging around that still works and doesn't chew up the tape as soon as you start playing.
