On my computer, I have 17,345 songs with a total playing time of 46 days 18 hours, 5 minutes. Everything from old blues, to big band, to 'classic' rock, to modern alternative. If I want to, I can pretty much spend all day listening to nothing but songs that are exactly 3:33 in length. There's still plenty of new music being produced, if you're willing to slog through dreck, you can find some groups that are really producing some fine stuff.
What ticks me off is that modern copyright law has pretty much done away with the concept of the public domain. By now, the vast majority of my music should be in the public domain. Dark Side of the Moon is 45 years old! The entirety of the Beatles catalog should be in the public domain by now. It's sad that we've let our government become the best that Disney's money can buy.
Well,you've got me beat.About 15 years ago I discovered CD-Rs (I'm a computer dunce).I also discovered that our regional library district allows you to search their huge collection by keyword,etc.
As a result I was able to amass a collection of about 5,500 songs...about 90% of which are from the 50's (my parents' music,some of which I love) and the 60's (my generation).It took a while...and involved a number of visits to various libraries in my area.
