Eleven from the iTunes and eight from the YouTubes, not bad odds. I would say my nephew Joshua would be the most obscure artist on the list, but he's up on The You Tubes as of late last month, while William Bell is not well represented. Bell is my favorite discovered artist from the Stax/Volt singles box set released sometime last decade.
The Elvis song was never a single, so no one has put it up on YouTube, though it comes from maybe my favorite of his early albums, Get Happy! The YouTubes are also scrubbed free of Van Morrison, although there are a jillion covers of his tunes, as it should be since he is a brilliant songwriter. The Pogues song is played on my favorite HBO show, The Wire, while the Nina Simone song is from the promo for HBO's Six Feet Under. Someone put a lot of sadomasochistic images with the Buzzcocks song, so viewer discretion is advised.
But if I were to feature one tune, I would pick that perfect pop song I Want You Back, still for my money the best song Michael Jackson ever recorded, followed closely by his love song for a rat, Ben.
