Buskers are often an excellent (if inconsistent) source of entertainment. An array of brilliant lyricists like Tracy Chapman have earned extra money by performing street side for passing onlookers. Here in NYC Tompkins Square teems with dreadlocked tattooed street punks offering excerable interpretations of American folk songs. Buskers are pretty diverse, you can see everyone from classically trained violinists to rappers busking, but one thing buskers are NOT is online. CD Baby CEO Derek Sivers posted a whimsical business idea on his blog for anyone willing to try it: an online collection of busker videos with a link to paypal on each page for donations.
