Audio over video/movie

Hi all,

does anyone know where to obtain an open source audio file for playing over my videos, embedded into the video?...it would be good to have 4 or 5 plain instrumental files insert-able like in the materials library for objects, that can then play music and embed to the movie file whilst creating the rove/.movie file.
