I haven't gotten around to Volume II (stuff-that-only-lives-on-CDs and/or 2009 discoveries-on) yet.
And half the artists are still cut off on this list, yes.
There is really, really no limit to how many you should put on there. Volume I of my list takes up 3.5 hours, personally. Or you may be normal and have way less sad music in general. I just want to know what you guys listen to, whether it is resplendent with explanations like The Music List, or just a list of titles and artists.
