To me the music is far more important. This song still invokes the same emotions to me now as it did when I wrote it in midi and played it through the Microsoft Midi Synthesizer, just like it would do the same in 8-bit.
Don't get me wrong a good mix and good production sound good and enhance composition and arrangement, but production is just the cherry on top of the delicious ice cream. Just look at pop music for example. That stuff is produced out the ass, but it's practically worthless as music in most cases because there's no focus on emotion via the composition and arrangement.
Although, I would probably at least attempt some sort of good production quality beyond what I normally do in my music if there were any way for me to learn how to do so. As of now none of the mixing/mastering tutorials I've found have been worth a damn. They all give these vague ideas about mixing and mastering without explaining how to do any of them. For example I don't know how many times I've seen you have to use EQ to cut out a space for each instrument. Well that's fine and dandy and a good concept, but how do you actually implement it without causing it to sound horrible, and what if you want multiple instruments in the same frequency range. It's all a huge pain in the ass, for such a slight difference.
That being said, if somebody was willing to mix and master my tracks professionally I'd definitely jump on that. But it's not very important to me.
