There's been songs that I didn't hate, but wasn't something I would find myself listening to outside of authoring. However over the time of authoring the song, and testing it I find myself growing to really like it.
That's happened a lot to me.
There's only been one song we've authored that I (I being Noble) just didn't enjoy listening to at all, and haven't played it outside of testing and reviewing.
So out of the 100+ songs we've worked on are working on, I think that's a pretty good average.
