This is based on my own experiences.
I feel you, when you start working with artists, I have had rappers and singers, singers that liked Brandy (Dark child synthy joints) but when they want tracks for themselves they want them to sound like Indie ari style, completely acoustic sounding without any synths...
Depending on the rap artist i deal with they want what most hear around their area, state or block for the most part.
Some rappers like something completely sampled off of a record, hell I seen so many that if you play a record they want to rap off of 40 seconds of the record simply looped and thats it!!!!
I mean man, i never had anything big hit off, but trust me i have dealt with a lot of artists of varying abilities and sat in on some sessions with very good artist, for me in a lot of instances artists have wasted my time or just were not whole hearted and serious about the pursuit of being very good, i have been pretty much in a state of pure instrumental focus for the last year or so and am contemplating wanting to get back with artists.
I do feel your pain, because right now the shit thats popular is the south feel and its been like that for longer than i can remember....
the typical rapper for the most part.
Is not really feeling the conscious Nas esque beat, a lot more will do a jiggy club beat that meets halfway between something downsouth and a simple melody done on bells or keys.
I think the real tight tracks are overlooked because one, the mindsets of a lot of artists(singers and rappers alike) are in a box, many will not do anything outside of the in artist or what they perceive through the media as hot, nothing wrong with that but it limits a producer that wants to either experiment, has a vision for his music and wants to completely start from scratch with an artist.
To finally to answer you on whether you compromise by doing production that is not usually how you do is by asking yourself 2 questions.
Does the music you produce define who you are and does only being able to do one style of beat define your skills and satisfy you?
If yes ,then keep doing you and do not compromise
If no, then you should expand your talent, skills and potential by experimenting with all types of music, yet invoked with your own style.
Do you enjoy making the same mundane style of beats and does that satisfy the majority of your clients?
If yes, then keep doing you and do not compromise
If no, then you should take some time to study what you bring to the table utilizing your style that could be implemented in the requested beat style of your artist regardless of your ability to produce a classic hip hop track and be happy making music of any flavor.
