The changes will actually help this particular song, since it's doing amazing in streaming, which now will count towards the urban chart.
Thinkin Bout You is also #5 in the R&B chart:

It might hurt Frank's other songs though, since he's unlikely to crossover and might not do well in digital sales, but the streaming is good at least.
