What role does music have in your fictional world? Can anyone play/appreciate it or is it limited to the privileged few? Is music imported from other worlds (whether or not there is a lack of home grown talent here)? Is music limited to, say, classical only?
In my fictional Fairy Kingdom, humanity is looked down on for its warlike and polluting qualities (difficult to argue that one really!), but things like music are a big tick on the plus side for us. Every species, including us, needs to have at least one redeeming feature. All characters need at least one redeeming feature too.
