Is there another player out that does this?
Yes, foobar have a plugin, which can assign/bind a new playlist as a queue-showing-playlist. You can have a big playlist with many albums and enqueue diffrent tracks, which are displayed at the queue playlist.
seekbar
When I try to seek through the track the slider jumps backs on its previous position.
It only works with realy big jumps like some seconds befor end of track. Same behavior with mouswheel.
Edit: Okay, found out you need to drag the slider to the wished position and release, but after release fast left click on the slider again to "confirm" the position.
