Dear ZZ Top: This song isn't just about having money but rather how you got it. And you got it by being a hardcore drug dealer -- those "25 lighters on [your] dresser" aren't filled with butane, no sir, but rather crack. You're going to empty them out, clean them, refill them with rocks, and then sell them to people who smoke crack. That's how you get paid, not just because you're awesome and your rims are super-shiny.
How did Top think their protagonist made "25 mill" and could afford "25 fly diamonds in [his] ring" -- by selling low-grade weed? Did they even think about it that much? My guess is, since they only vaguely mention the "toil of a ghetto hustler" when talking about the song, they didn't consider exactly what he was hustling, only that he was. It would certainly explain the title change. After all, who gives a fuck about a bunch of 40-cent plastic Bics when there's money and cool-ass cars and women wearing just enough clothing to satisfy the legal requirement? You know, despite those lighters being the song's entire point.

DJ DMD needed the money to finally upgrade to CDs.
Hip-hop is all about authenticity, and three rich white dudes pushing 70 unknowingly yakking about street-selling hard drugs seems the exact opposite of that. Unless, of course, ZZ Top's secretly breaking bad and we don't know about it. After all, staying sharp-dressed ain't cheap, and nobody buys music anymore. But plenty still buy drugs! It's either that or be totally out-of-touch and irrelevant -- when you're a rock star, I'm not sure which is worse.
