2Pac & Notorious B.I.G. - Runnin' (Street Version) (1995) sampled Booty's Rubber Band - Munchies For Your Love (1977)

Artist:  2Pac & Notorious B.I.G.
Song:  Runnin' (Street Version)

This is a rare song because it features 2Pac and Biggie on the same track.  It is taken from the compilation album "One Million Strong".

Artist:  Ill Al Skratch
Song:  This Is For My Homiez
Year:  1994
Album:  Creep Wit' Me

Remember these guys?  Their songs got abundant airplay in 1994.  I want to mention the sample was also used by Scarface "Now I Feel Ya" and Fat Joe "Say Word".

Artist:  Bootsy's Rubber Band
Song:  Munchies For Your Love
Year:  1977
Album:  Ahh...The Name Is Bootsy, Baby!

2Pac and Biggie used the guitar note at 0:15 for the introduction and then the 4-bar loop starting at 0:19 for the rest of the song.

Ill Al Skratch used only 2 bars starting at 0:19 but occasionally played the keyboard part of the sample to make it sound like the 4-bar loop.
