If you are talking about mainstream hip hop you got a great point. This is why I avoid mainstream music for this very point, but yes I do cave in once in a while if the song is catchy. Music on the mainstream level are just made to please the ears or the mind, however you look at it and this is only to bring in more money. I do listed to mainstream artist though, but it is usually the songs that don't make it to the radio because I feel the lyrics are much better quality than that of the radio.
The lyrics of mainstream music to me seem to be about the same thing, partying every day. This is what the basic consumer or listener wants because it just sounds good. If you look at any album, they will have a whole bunch of music that would not normally be played on the radio because of its content, and then you have a couple songs that just blow up the radio. Every other song played will be this song it seems like, and they only do this so that they keep the loyalty of their fan base.
As far as the instrumentals, I usually don't have a problem with them unless they have an irritating beat. For instance, a song that I disliked because of its beat was Blame It (On the Alcohol) by Jamie Foxx. This beat just was something that I could not imagine why people would like this song, but i guess since its about partying everyone seemed to like it.
I just noticed this trend as you have, and I'm sure that other people have noticed it too, and avoid it for the same or different reasons that I do. Thanks for your question, I'm very pleased someone else has noticed the same things that I have been noticing about music these days.
