That wasn't always the case though especially in those Motown and early days where you couldn't tell with a clear distinction which genre the song was apart of. The bolded in didn't particular start happening until later years.I hear what you are saying but I must respectfully disagree. When it was a collaboration of r&b and rap which had been common for a long time it used to still be a clear distinction what you were doing or what the two artist were doing. Now it's literally the same lol.

You out of touch. Just say that.
