I've never been a guy who wants his lyrics handed to him, so I like how the CD sounds. Even if it were all arrant nonsense, I think that the sound of the singer is gorgeous. Calling the vocals "lush" is no exaggeration.
A lot of my favorite bands do songs where the lyrics are little more than gibberish because sometimes the sound of the words can be far more important than content. Tree Wave manages to have more depth than that by having something interesting to say while not making it totally obvious. More to the point - it's worth exploring to find it!
