It would be super cool if us users and your staff could add Tag’s to the sound sets to make finding “just the right sound” easier. I think the search feature now just searches by titles of tracks, which usually will help you, but there are times I really have to hunt down the sounds I want.
Using multiple tags in a search would help us narrow down the field of options even more. For example searching Vikings+Space+battle+dragon or Elvish+holy+Temple+ruins might direct us to a few sound sets that we can combine to make new moods. Would also be cool to see what other users have found for moods in their games.
Just my 2 cent idea for now.
