Timed cue for ending of song

I just purchased this app for its ability to change the speed of music. I also love the integration of Spotify. However for party play lists in any dance studio having the ability to decide when the music should fade in auto mix without having to manually do this would be great. Giving the option as it is now where it can fade a minute before the end is not helpful. Some songs are much longer than others. So if the amount of time could be entered in, this would make your product a much user friendly app for all dancers.

Ps I noticed something like this, was mentioned 3 years ago in the community forum but nothing obviously was done about it. So out of good faith I had purchased your product, in the hope this would change.

This is a great, great idea. Please add this.
