I think that the problem, with these group and matching puzzles, is that it's hard for puzzlers to save them in a practical form on their HD.
I usually download the images of the puzzles I'm interested in in a file. No problemo for ordinary puzzles.
For group puzzles, the best would be to save and print a whole image of the first post, so one can have it with him when he does his research. And that's impossible. And also to save and print the post by the author of the puzzle where he states which ones are solved, and which ones are not.
So, in order to be comfortable, you'd need to have whether these prints, whether a computer with three screens: one for the images (and still they don't fit all in a screen), one for the results and one for you research.
I forge to say that your music puzzles are really tough, but that is part of the fun, naturally.
