Comment 5 for bug 1114643

In this context our "Assume constant beat tempo (Recommended)" is not suitable because with non constant tracks it will be pretty useless at the end of the track.

For me one bullet point on this is that we knew the kind of a track.

Can one explain what is the use of this feature and why it is recommended and default?

It looks like we have two kinds of tracks:
1. Constant Beat grid and master clock able. (Breaks and other short therms tempo shifts are allowed)
2. Non constant tracks like live recordings or "Zorba - Sirtaki" with different BPM at start or at the beginning.

Mixxx should be already able to distinguish between those types.
What about reflect this information in the GUI and for an upcoming beat matching Auto DJ?
