First of all, thank you very much for this great and free software!
Several bugs and suggestions:
1) Sometimes it shows very different songs as being similar, e.g.

.
2) Thus it would be nice if the waveform comparison algorithm was improved
3) Thus it would be nice to have an option to scan full tracks (not only the first 60 seconds)
