Systems and methods for filtering media containing objectionable content are described. Marker files that list the times objectionable content occurs in audio content (such as a song, podcast, audio associated with a video or television program, or the like) can be stored in a user device. When a user plays audio content for which a marker file exists, the system can automatically filter out the objectionable content marked in the marker file from playback of the audio content. The system may also provide functionality for the user to specify a level of filtering to be applied or even specific words to be filtered from audio content.
