Fade music out, fade music in

1

Im working on a project where i have to develop an audio application for an android smart phone, but i have to present a mock app so i designed it in flash. I have a rough app where it loads the song, plays, pauses, foward, and previous, but im stuck :puzzle: flash isn’t my first language, as you can tell from the attached .as file there are two things i need help in one is: when one clicks the next button the audio clip from the current song should fade out and the next song should fade in while the other song fades out. second thing is i don’t know how to get a working seek bar for the player. Any one mind helping me or pointing me in the right direction.
