Ok so I have an activity where I display a song that's playing, and I created another layout for landscape mode, I have an imageview that displays the album art from that song and a title in the actionbar, all display information of the playing song, but when I rotate the screen and then rotate back to portrait mode and switch song with my next button and then rotate on that other song, it still displays information of the previous song.
My first activity (displays all songs)

How can I update the album art on rotation, it only occurs when I rotate the screen, in portrait mode it all works fine and updates the information when I change the song.
