I think subtlety is a good thing when it comes to anything, but I do happen to like those tracks as well. While as part of the soundtrack they sound a little too square wave dominated, within the gameplay itself, it tends to work out pretty well, in my opinion at least.
But not everyone is going to agree, and that's totally cool! A good example is the soundtrack to "Assassin's Creed Brotherhood". While the tracks themselves are a little annoying to listen to, in the context of the game they work incredibly well.
But you're totally entitled to your opinion, and I definitely appreciate comments and criticisms! They help me become a better composer, so thank you!
