First I would verify where they are in the renovation, is it complete? all I've found says it is not. You can't trust anyone on the phone. The proposed schedule was half the suites done first then other half done last. The Disney website still lists the old bedding for the suites. This usually happens when renovations are not complete and will not change until the last suite is done. This way if you end up with an old suite they are covered by what they advertised.
I am not a fan of Music but I stay in regular rooms which are at the back. The plus here is the suites are up front so basically very preferred location. I think the new suites are nicer than AOA because the sofa is a bed, not sofabed and the kitchen is legit it's own space. [I do bring food and we eat in room]. If the room and bedding are your priority then I would save the money but use it to enjoy other things as I likely wouldn't hang around the resort any. I would use for special events, dinners out etc.
If hanging around the resort and enjoying the pools are an important part of your trip then I would stay with AoA. The pools are top notch for value and the quiet pools are better than even the deluxe quiet pools. You have the skyliner for two parks rather than long bus rides.
If I'm not guaranteed a refurbished suite then it would be a hard no for Music. But if they are I would actually pick Music but spend no time there other than in my room ... use the extra money to do some fun stuff.
