Not who you're replying to (but I'm in the same camp). I use the album art as decoration, but the music is the first selection criteria. The music has to mean something to me first, and then the album art just needs to "pass".
I have young kids also, so I try to stay away from violent or scary album art.
Don't know if this is sarcasm or not. If you have 23 req/day, then there's no tech problem to solve. Whatever you have is good enough, and increasing traffic will come from solving problems outside tech (marketing, etc)
