Hard to figure out the new one

1)The sound quality is not as good as before
2) you can no longer here the iTunes sample
3) there are no instructions of how duets work
4) Ive invited people to duet but they do not show in my profile
5) I used to get a lot of notifications of people listening to my songs but not anymore what s up with that!
6) go back to the old version and work on this some more
