Music is commonly used within videos, podcasts and presentations. While we encourage the use of musical elements in your multimedia projects, one must be careful to ensure that the music they re-purpose isn't covered by copyright.
Below is a list of resources offering music that is either free of copyright ownership by a third-party publishing company, or is licensed to allow for reuse under certain stipulations (Creative Commons is a common licensing method). Please refer to each site for the specifics of whether the music they offer is completely open-source or is under some type of attributive licensing.
