Save speed adjustment in music manager

[vbds]

The music manager allows you to save many attributes of each song, even a volume adjust, I would also like to see a "speed % adjustment".
Like the volume adjust, the "speed % adjustment" would be the default speed for that 1 song when it is played.
Once a "speed % adjustment" is set in the music manager it becomes the "normal" for that song.
When this is done the user can change the BPM to reflect the "speed % adjustment".
I believe the the song play time may also need to be adjusted in the same was as when the song is played and the speed is adjusted.

This can be done, though figuring out the duration of a speed-adjusted song is very difficult.

I say don't worry about the fixing the duration, just allow save of the speed-adjust.
Maybe- latter you can re-look at duration.

Thanks for the consideration of this request.
