Fck thats a hard choice, me and my boys used to freestyle over the 'Phone Tap' instro for years back in the day!!! haha
Ahhh, think I'll go with 'Keep Their Heads Ringing' as a beat as its more of a Dre sounding beat with the high pitch synths and funk but I could change my mind in 2mins...
'Phone Tap' definitely the better song though...
