Remember "popular music," is not Royalty Free. Anytime someone plays a popular song by an artist that artist is collecting royalties. You can use commonly used songs but only 10% or 30 seconds of the song, anything else is a copyright violation. Remember if you choose to not use Soundzabound or another royalty free site you can only play your presentation for educational use and it cannot be posted on the web.
