CSCHOOLLAND  The technology is oustanding. Even the presets for different speaker types (internal, external, headphone) are fabulous (though my iMac seems to fall somewhere in-between). This is a great investment for anyone wanting to automatically improve the quality of your digital audio and get the most out of your high kbps, without paying hundreds of dollars or more for a state-of-the-art sound system (or, in addition to, why not?).

As for customer service, some have complained about the activation limitations with no customer support. After using iWow for years, I began experiencing activation issues today (I boot externally between two machines), contacted CS, and got a helpful reply TEN MINUTES LATER. They've got my support!

CSCHOOLLAND  Great little tool, but still needs stabilization. Active tagging ends up stalling if no lyrics can be found, and the program insists on reverting to showing me lyrics for the selected song rather than what's actually playing. It just doesn't switch nicely between view current, view selection, active tagging, and edit text. Also, if no song (or a radio station) is playing, a never-ending array of error dialogues pop up when in active tagging mode. Very frustrating.

All I need is a program that fetches and displays the lyrics of whatever song i'm listening to, and perhaps occasionally find lyrics for a batch of songs. That's all. Get Lyrical seems able to do that much of the time, but there are just too many niggles that keep cropping up.
