Have mercy on me if this has been beaten to death or the answer is obvious, as I'm 22 and just starting to get into the Rolling Stones. My question is this: on the first "Hot Rocks" compilation, the last two songs are Brown Sugar and Wild Horses. These are Rolling Stones Records (or Virgin, depending on how you look at it) tracks, not ABKCO. Why is this? Is it because of some sort of unfulfilled contract obligation?
