Systems and methods are described herein for displaying subjects of a portion of content and searching for content related to a particular subject in the content. Media data of content is analyzed during playback, and a number of audio signatures are identified. Each audio signature is associated, based on audio characteristics, with a particular subject within the content. The audio signature is stored, along with a timestamp corresponding to a playback position at which the audio signature begins, in association with an identifier of the particular subject. Upon receiving a command, icons representing each of a number of audio signatures at or near the current playback position are displayed. Upon receiving user selection of an icon corresponding to a particular signature, a portion of the content corresponding to the audio signature is played back or a search is performed for content related to the signature represented by the selected icon.
