For the past year, I've been using the incredibly powerful gmusicbrowser Linux application for audio library management and music playback. But the program has always crashed every time I exit.
This evening, I found an active bug report for the issue, and through some creative troubleshooting resolved the problem. Now the application runs flawlessly!
What drew me to gmusicbrowser was its impressively fast and fluid handling of large libraries (150,000+ tracks), and its 100% customizable interface which I've maximized to take advantage of every possible piece of metadata I could ever care to access.
This made my day!
