These would fall in to a backing track area, because of the repetition of everything. You do need to pan each part to their own perspective area in the mix and don't be afraid to spread them out good from each other, there are lots of spaces you can use. And get something happening throught the piece, so it doesn't just sound the same all the way through. This might be a good head nodder in a dance club, but even they mix everything up and add excitement to the mix, so look toward excitement and you just might do well.
Peace and Blessings, John
