Yes, I can confirm, the 5 styles I bought were all well made. Not just technically, but had obviously been done by someone with real musical and arranging chops. The intros and endings were a pretty accuratel reflection of the original recordings, and the main variations all good. Good enough that if you are willing to play your own intro/ending you will almost certainly find they work well for more than just the song named.
They give reduced prices when you buy several, and at around $5 each are excellent value. And the process of buying and downloading was pretty slick, and another point in their favor is that they take PayPal. So if you already have a PayPal account, payment is both fast and safe.
I had never bought from them before, and knew nothing about them prior to this purchase, but would definitely recommend them based on this experience.
