The present invention relates to a system and method for displaying visual advertisements with played data, and in particular, for displaying such advertisements in the format of video data while electronic files containing audio data and/or streaming audio data are played on a computer. A method and a system for playing a first type of data, such as audio stream data, for the user while simultaneously displaying an advertisement in the form of a second type of data, such as video data. The system and method enable advertisements to be displayed while music is being played from an audio file by the computer of the user, thereby providing an alternative revenue source for the owner of the rights to the audio data. Furthermore, since the advertisement is in a data format, preferably video data, which is different from that of the audio music file, the display of such an advertisement does not interfere with the enjoyment of the music or other audio data being played.
