You ppl are reading too much into it. And unless you ever been posted up in the kitchen cooking away, you could NEVER understand what CRACK MUSIC really is.
For alot of ppl Crack is the only way to get substancial income ---> link tht to beats.
If someone hands you a pie, but when you cooking it you KNOW there's potential for two in there, you gta GRIND it out ---> If someone hands you a sample...see the link! There's many other ways to deter the meanings of Crack Music (addiction being the most obvious) but unless you've lived it DO NOT USE THIS TERM (same rule applys for white ppl and the word nigger, try it in the next couple hundred years, **** may have blown over by then)
