1. A method comprising:
- detecting, by executing an instruction with a processor, a watermark in a first media composition, the watermark encoded with a word present in an audio track of the first media composition, the word being audible during playback of the audio track;
retrieving, by executing an instruction with the processor, the word from the watermark;
determining, by executing an instruction with the processor, whether the word retrieved from the watermark matches a keyword; and
presenting, by executing an instruction with the processor, a second media composition when the word matches the keyword.
