"Stop Your Sobbing" is better known as a Pretenders song, but it was originally by The Kinks. I also have a version by Jonathan Richman here as well.
"Every Little Bit Hurts" is a 1964 Motown ballad by Brenda Holloway. I also have two covers here by The Spencer Davis Group featuring a very young Stevie Winwood and another later version by The Clash.
The peppy Pixies song "Mr. Grieves" gets an outstanding a cappella take by TV On The Radio.
Other songs that don't repeat: a mash-up of two tales of big city striving--Notorious B.I.G.'s "Juicy" with Frank Sinatra's "Theme From New York, New York", global striving with Tears For Fears' "Everybody Wants To Rule The World", J Dilla and Madlib's collaboration as Jaylib with "The Red", King Koba's upbeat "Station Underground News", Danger Doom's witty "Mince Meat", Creedence Clearwater Revival's rhythmic "Keep On Chooglin'", the wordless "Regatta De Blanc" by The Police, Paul Simon's more reggae ("B") take of "Think Too Much", Ghostface Killah's unexpectedly tender"Big Girl", Elvin Bishop's sweet "Fooled Around And Fell In Love", an alternate take of John Mellencamp's mournful "Jackie Brown", Neil Young's steel guitar-inflected "Hey Babe", Rilo Kiley's yearning "The Absence Of God", and Cat Stevens' peaceful "On The Road To Find Out".
