Comment 2 for bug 1114643

Thank you for your DJing hints!

But what does it mean for the Mixxx GUI?
What is the best way for Mixxx to support a DJ in doing it like proposed?

It looks like It is important to mark those tracks.
What about display a additional "~" in the BPM coloum or display the BPM range?
Or change the color or those non constant beat grid?

What should happen if we introduce a "Master Sync" clock in an upcomming version.
And how should the beatmaching mode of the upcomming Auto DJ deal with it.
