A brilliant tool for both amateur and professional musicians! Its obvious that its been designed by a musician and / or sound a Tech.
So many useful features which are easy to use.
One feature I would like to add would be to automatically normalise the volume for each track on each playlist. Sure, this can be done using the track volume in conjunction with the master volume, but its relatively time consuming.
