Sheek Louch aka Mr. Money Pants

Brief programming note: Due to circumstances beyond my control (the phone, TV, etc.), I will be out of the office for tonight's Real World season finale. If all goes as planned, I will DVR it and have a summary up by midnight CST, but I'm not making any guarantees. Sorry.

I recently received a copy of Sheek "The Birthday Boy" LaRouche's new album After Taxes and will probably review it at some point, but not today.
Listening to it, I notice LaRouche likes to boast that since he's on Koch, he receives $8 per album sold. On "On the Road Again" he raps, "Plus I seen how these Down South niggas do it/ $8, shiiit, I could get used to it."
In a recent interview with one of these fantastic rap sites, LaRouche remarked:
I got the #1 independent record in the country right now. I sold 40,000 records in 7 days. That's $8 off of every record. That's the reason I went indie. I'm not trying to see 33 cents off every record.
I guess my question is: Is this true? Do artists on Koch Records really get $8 for every album that they sell? And if that's the case, how come all artists aren't on Koch?
I'm assuming this isn't actually true; artists on labels like Koch make more than artists on major labels, but not anything like $8 per album. But I figured somebody reading this - artists, label people, perhaps someone from Koch, might know more about it than I do.
So what's the deal here: Is Sheek LaRouche full of shit or what?
