Usually I try to shoot for things that no one else does.
Not a smart plan most times if you're one that does it for the fame or notoriety.
I mean a lot of my sims bases off of gimmicks anyways and most of them aren't incredibly in-depth or using negative stop/BPM tricks but enough to at least mess with the person enough while still being fun. There are a few times I'll cave and do a sim to something that everyone's looking at just to maintain the status quo but I usually like to delve a little bit farther than the norm.
I mean check this out.
That posted, I also tend to use whatever I make to promote other artists out there. I've done this a few times but people that I talk to enough that would benefit are people like Detach or Bouche. If you've got something I like and I have the time, I usually like to get some feedback coming their way about their style. Generally, they turn out to be real good in the long run after a few years.
So it's kind've a win-win for people that get a hold of me that are artists in that regard...IF you have something that would be considered worthy of a sim, that is. I've got preferences to songs like other people but I'm usually quite open if it's got beat and could theoretically go to decent steps.
