check out this website. it's a database listing the BPM's of 25,000 major tracks, which for most of us could really simplify the acapella finding process..

it doesnt have everthing obviously, but it tends to have the major tracks from an artist that you'll find on acapellas.co.uk or similar sites, so its pretty damn helpful.
