Today is Day 1 of Music Thing's official "Let's cheer up the world of music geeks" campaign, after the weekend's sadness. Our first salvo comes from Jan in Berlin who writes: "Check this out. Beastie Boys acapellas, complete with BPMs (except for tricky songs like 'Root Down') for free download. The background image alone is worth it." Send further thoughts to: cheerup@musicthing.co.uk
