Using star features is just leveraging your tools鈥攅very great craftsman does it. Refusing to use what's available isn't integrity, it's stubbornness dressed up as principle.
Star features are smart strategy: they hook attention fast and fund the deeper work. If the core stays good, using a headline feature is just good marketing.
The music industry is a business, and cross-pollinating fanbases is the fastest way to grow. If an A-lister wants to jump on your track, you'd be an absolute idiot to say no.
Smart strategy all the way. Star features get you noticed and paid faster than grinding in the dark.
