How much do you think the top producers are worth? i.e. Timbaland...

[Dids]

If you're talking about producers, a lot of those guys are making sick money just selling beats. If you believe what people are saying in songs between 50-200k depending on who you are. Timbo being at the upper end of that threshold.

T-Payne is apparently rich as hell just selling ring tones.

Album sales are about the least effective way to make money in music right now.
