Absolutely top notch, perhaps the only thing missing is the ability to play with a capo. Sometimes the songs in the original key are almost unplayable.
LubosPAV, I have the original Riffstation, but it looks like this one is the same. You can use a capo easily. Select "Cord Viewer" (middle right), then below that you'll see "key shift" then further down, you should see "capo". If that those are there in your version of Riffstation, you're home free. You should now be able to adjust the key and then adjust the capo so you have cords that are more to your liking.
