is there an official stretch and bobbito freestyle compilation?

i have downloaded stuff here and there in the past separately by artist or if i search hard enough but never all together....i have a nagging feeling i have random obscure ones i'm still missing, like rap city freestyles, tapemasters made a 'best in the booth' mixtape, but it's not everything and not everyone was recording BET all the time whenever a guest appears with a freestyle...the beat is unknown or obscure as well
