Does it seem to anyone else that some CDs
scratch easier than others? I remember when I first got Harmony, only a couple of months after I got it, "No Mistake About It" would skip whenever I played it. Summertime Dream (my 2nd oldest album) no longer plays, and neither does Sundown (only the first 6 tracks, after that I might as well put in another disc). They lasted about a year or so of taking in and out of the box and pushing them in & out of the CD player.
However, Gord's Gold 2 (the oldest I've got), and A Painter Passing Through (not one of my oldest but one of the most frequently played), plays great. GG2 looks a little bit scuffed up when you turn the disc over, but A Painter looks almost like it's brand new (though I can't say the same for the box

).
It also seems some CDs can play with a scratch better than others. As I mentioned above, GG2 has a few scuff marks and miniature scratches, but plays fine. Seems like when it comes to burned CDs, the teeniest, tiniest, most microscopic scratch will cause them to skip.
