Are they anything like Micro chips? Can I eat them??

As one who can spend four hours sorting things into groups, I dare not delve too deeply into this, but basically, if a song/tune overlaps into 2 or more groups, you have a good song/tune, and you should proceed to sing/play it to death.... figuratively speaking of course.

I once filled an old picture hook hole in a white wall with toothpaste - SO didn't notice for over a year..... once it dries, it just looks like ordinary filler. He only found out when he wiped the wall down ready for painting it.....!
