Mix...suggest you check out franchiserecordpool.com...Membership is about $20 a month. They have some old and new school music and videos.
At that price it should be a no brainer for you to show you have a legitimate source of music and video.
That's an awesome pool .. I may join that just to pick up the back catalog. My current one (IDJPool) doesn't go back more than the past year for most stuff.
