Upon hearing that Warner Music Group recorded-music bigwig Lyor Cohen had sold 23% of his stock in the company–and raked in a $6.8 million payday as a result–one former employee said to me, “If i still worked there, I’d consider setting the building on fire. What a boost for company morale.” Not to mention stockholder morale–WMG is currently trading 8.5% lower than it did yesterday. Well, at least there’s the dim future hope of all those Guitar Hero royalties, right, guys? [Reuters via WP]
