I have now adopted using a random integer generator program to help me decide what to listen to from my collection. Since I have a database of my collection on an excel spreadsheet, I simply run to program to generate a spefic number of integers that correspond with the location on the spreadsheet.
So if I can't decide for myself what to listen to, I certainly can't offer any useful opinions.
I also have boxes of CDRs from my misguided days of CDR trades that I have not listened to. A few months ago I started converting them to mp3 with the thought that maybe that would make it easier to work them into the listening schedule and also save space - but the truth is that I rarely listen to mp3s.
I am not being helpful, am I?
for what it is worth, I would say fill up your case with a random selection of all of it.
