Is the limited duration the result of the low song potency (+5) and will it improve with the stage 4 and 5 versions of the prime?
Yes. Nothing can be done until stage 4.
Hmm, I was afraid of that but couldn't find anything online to confirm it. Thnx for clearing this up.
I managed to put Aria last in line in my 4 and 5th song setup, that just gives me about 30 seconds to re-sing when Nitro is available again. Now to make sure the dummy song is a short one so it actually gets overwritten by Aria!
Thnx Dodik!
