All the song settings i made on iTunes local library (song > right click> get info> options), the volume and start-stop timestamp settings have been ignored ever since i upgraded to iOS 10. Those settings are working fine in iTunes, ios 9, ipod classic. I had noticed this problem since the release of iOS 10. I have submitted a bug report to apple and i also contacted applecare customer services, the respond i got is not very positive hinting that if this is not a mass issue, probably it won't get a fix. This is a very serious problem to me as I have a lot of live performance songs and they often have very long crowd cheering, also as a headphone user, some live songs mixing are just ear-explodingly loud, that's why i will have to make some settings on iTunes. I have never used the music app ever since.
