Hittade lite mer info om detta på Apples forum:
"If you want to resume playback in the middle of a track, you need to Get Info on the track in iTunes and make sure "Remember Playback Position" is checked. Most people don't use this option for music tracks, but you are free to configure yours however you want."
"yup. in version 1.1.4, it seems that the Music App is kept 'running' so that if you pause a song, watch a video, then go back to it, it still is playing the previously paused track and in the current position, even though the 'Remember Playback position' is not checked in iTunes. I miss that. It was removed as of 2.0"
Ska testa detta.
