Almost perfect, a couple of requests – Sleep Sounds HQ: relaxing aid Review

Really wonderful app, I highly recommend it. However, I would like to see a way to add my own personal ratings for each sound or otherwise mark favorites. Also, I would like a way in browsing the library to see which I have already downloaded, please. Still 5 stars, though. Excellent work!
