Well if you mean technical expertise then most pop music is absolute crap if you compare it to classical music, there is always something more complex. Just because something is more intricate and crafted doesn't mean it is 'better' because a person who loves one genre may hate another. Personally I like rock/pop music mostly, but can easily listen to classical music too and apreciate it, but I hate stuff like R&B/Hip-hop/Rap because I think it is terrible, whereas some people may be the opposite. Just down to personal taste.
