Forward and back 15 second buttons for music

[alexilaiho]

Just like you can jump back and forward 15 seconds when listening to podcasts, please enable this feature for music (or at least give us the option to turn it on or off). The sliding time bar is cumbersome to move back and forth and for practicing musicians who are learning to play songs it would be super valuable to be able to jump back by a set amount of time to replay part of a song. Or even just for someone listening to a song and wants to quickly hear something again with a single tap.
