Since the dawn of advertisement, there has been a constant relationship between visual content and music.
Virtually every television based advertisement produced is accompanied by a soundtrack, whether that be a conventional piece of music, or just soundbites or effects.
Below is a link to an interesting webpage that discusses the use of music in advertising, adding a level of critique to a number of examples from years 1970-present.
Also well embedded within the advertising world is the concept of “soundalikes.”
Soundalikes are usually short pieces of music that bear a recognisable resemblance to an existing song, but are composed so that they lie outside the parameters of anything which would incite legal action from the copyright holders of the original piece.
The website linked below discusses soundalikes a greater detail.
