I'm not sure what you where trying to do, but there's a whole chord recognition service written in Haskell: http://chordify.net/

Apart from that, I have written many production grade Haskell application, and I can not agree with you that Haskell is getting in the way. I admit that when learning Haskell I sometimes had that feeling too, but basically that was just me thinking about the problem too complicated or in a wrong perspective. Now that I am past that point Haskell is super fun to write, very productive and results in extremely maintainable code - it is just so easy to refactor anything you can imagine - and when it compiles again you are probably good to go!
