I'm a composer who works in film/games. I can assure you this is exactly what I'd like people to do when they listen to my music. I spend 99% of my time trying to create good musical ideas, and I spend 1% of my time getting the mix down. I get criticized (rightly) for this quite a bit, but it is hard to care about someone sitting in a >$10,000 labyrinth of sound equipment when I'd rather write a catchy tune.

Then again, when I write sheet music I have to endure some of the most soul-crushingly awful midi sequencing in order to check my work, so perhaps I'm too tolerant to terrible sound quality. Still, I'd rather people listened to the music, not the sound of it.
