I have many many recordings. I mean, I'm interested at a good audio quality. I hate bad sound,you can't enjoy freddies voice. that's all. My feelings are 20 years the same. Since 1985. Stay sweet:)
If I understand you correctly, you have been a Queen fan for 20 years and already have some recordings.
So, what's the best quality one you have? We can then suggest equally high quality alternatives....
