Here's something I find somewhat annoying that's CD related.
I've bought a few CD box sets over the last 2 years.
A 16 CD Cecille Ousset (The French Pianist) set in particular and yesterday, a set of Rachmaninoff's 3 Symphonies and 4 Piano Concertos and a couple of other sets.
The CDs in these sets are in cardboard sleeves inside a box.
The CDs are so tight in the sleeves, that they will not tip out at all. You can't shake them out either.
If you insert a finger to miss the playing surface and reach the centre of the CD, they become even tighter.
The first remedy I performed, was to take 2 old CD/R that I don't care about, place them together and repeatedly force them in and out of the sleeves of the 16 CD boxed set, to wear them in. That worked well. It did leave cardboard dust inside each sleeve but it took about 40 minutes to do all 16. Now the CDs easily slip in and out of the sleeves.
I've taken to carefully slicing through one edge of the sleeves now when they arrive like this. But they were so tight originally, that there was no way to avoid getting finger marks on the CDs.
This is somewhat annoying that CD sleeves in such cases are not quite large enough.
