The Naida usually defaults to a version of Autosense (global?) which is meant to be good for most situations. Personally I’d leave that in the first slot and fix your other preferred program in the second slot.
The slight problem with putting the music setting is that you basically turn off all the speech processing. Now this will probably sound nominally better, but your subjective evaluation is possibly hiding the fact that you need sharper (and possibly more uncomfortable) sounds to actually achieve you full prescription.
The DSL i/o always used to be the default for paediatric fitting so tends to have a good higher pitched response, which may help with the speech clarity too.
