Simon is pretty much on the money in regards to the stated concerns.

We have filters in place which will restrict music files to a minimum of 128 kbps. This, of course, isn't the only option for our members. We'll scale from your everyday, typical mp3 file (128 kbps-320kbps and beyond) on up to OGG and FLAC files. Of course, there will be no "premium" for this higher quality of sound, as you've seen on other channels of distribution. These tracks will remain 99 cents. In that regard-- and as far as quality assurance goes-- there is nothing to worry about.

Secondly, we have all legal aspects covered. While I of course cannot delve too much into this, our system is perfectly legitimate and set to shake things up a bit.

I hope this clears everything up. If you have any other questions or concerns, I'll be happy to field them. Cheers!
