We have multiple audio related tags:
Out of these tags, some of them are quite clear:
music-production clearly covers virtual instruments, digital audio workstations, sequencing software, etc.
music seems to be at the more average end user end of the scale - media players, media library software, that sort of thing.
And then some of them are a little off key and probably need fixing:
audio appears tagged with one of the other tags in all but one instance
composing covers sequencing, essentially - I think this should be merged into music-production and a synonym created.
