audio files: starting playback where left off

[mrmjorizing]

Hi, i want to be able to playback an audio book, stop it, exit the music player and start off where i stopped. the default music player has no slider bar to choose the point you want to go to in an audio file, or book marks to do this, and none of the music players i d/l have a slider bar. Is there a free WP8 music player which can do this?

Thanks.
