I had the impression that AC radio was evolving towards CHR in the States (KIIS-cuts between soft songs).
In Europe more and more AC stations are turning back to European based production houses. Vocal clearity, solo’s, brass when it has to be latin: it’s all here.
Here’s a compilation of what European AC radio sounds like today. Cuts from Brandy, Moonworks, RW Europe (they seem to produce very different from Seattle studios), Wisebuddah, Top Format and others.
