I am very interested in being able to shortening songs within my own playlists. I have a playlist with duration of 4 hours. I would like to bring it down to approximately 1 hour. I can do this by removing a lot of songs. However I would rather - somehow - be able to shortening the song on the playlist, one by one, so the total duration is brought down but the number of songs contains. Is this somehow possible? I have activated "crossfade" which works great! Another option could be to - while listening to the playlist - tap on the device/app to the next song, but keeping the "crossfade" option. This is currently not possible. Anyone who can assist?
