Comment 2 for bug 1457746

Thank you for offering you help.

Reproduce:
* play a track in Mixxx
* close Mixxx
* cut some samples from the beginning of the track (using e.g. Audacity)
* Play this track again

What happens:
Beatgrid and waveform have an offset, (still match the old track)

What should happen:
Mixxx should detect this and reanalyze the track.

I think the same will happen if you replace the track with a completely different one.

Todo:
* setup a powerful development environment.
* Analyse why it happens.
* I think we have already some code to detect some of these situation in Library scanner. Check how this can interact with this issue.
* Propose a solution.
* Code it.

This will help to start:
