Circular sound

This is me being all artsy. In fact I yet again had a pretty uninspiring day with regards to a blip. So thought I would blip one of my annoyances.
Discs...cds....dvds... and scratches! At least with videos the picture would just go a little fuzzy if it was damaged and cassettes would kinda sound slurry and possibly get chewed up in your walkman! Now if a disc is bad, it simply doesnt play! Whats that all about! (But then again it used to be annoying having to manually wind a tape on if it got all jammed up inside lol!)
So this is my blip! Hooray for unscratched discs!
