Remixing rights, sight and sound

For the remix assignment, my idea is to grab a song from the Internet Archive's live music pool, look for CC licensed images on flickr tagged with the title of whatever song I grab, and then mash the results up in a neat video.  I think this will be a cool way to experience the song, as well as see what people think the song "looks like".  Kind of unrelated, yet maybe relevant:  A while back, I made a song using FLStudio and then cut up some video that I shot in Paris, and came up with this.  My idea for the remix project is kind of based on this abstract-music-video structure.  I posted the video on YouTube, and until now have never bothered to read their terms for user submissions.  I apparentley granted YouTube: "a worldwide, non-exclusive, royalty-free, sublicenseable and transferable license to use, reproduce, distribute, prepare derivative works of, display, and perform the User Submissions in connection with the YouTube Website and YouTube's (and its successors' and affiliates') business, including without limitation for promoting and redistributing part or all of the YouTube Website (and derivative works thereof) in any media formats and through any media channels."Not to get too far ahead of myself, but that (as I understand) means YouTube could use my video to advertise for them, generating revenue that I would never see a piece of.  This also grants them the right to create derivative works, which is the concept behind this remix project.
