I agree with Marek - the current behaviour is good and won't "surprise" you while editing if new song gets played...

I will DEFINTELY like to see that "open with notepad" button - it would be great: you could still edit & save the original text file in the cache folder, and you'd also have that useful "save as...".
With the added benefit of reducing the bloatness - it's a winner
(if only could this #$@% karaoke thing could be totally exterminated too...

Thanks for this excellent software !!!
