The fact that it was a torrent is immaterial. The disk itself isn't faulty, the way you burned it is. I presume you used something like iTunes to burn it? If you didn't I suggest you do. If you use iTunes, insert a blank disk and it will appear in iTunes. Choose the songs or playlist you want to burn and click burn in the lower right hand corner of the window. It will as you what kind of burn you want to make (Audio CD, mp3 CD, and Data CD). You want to choose audio CD and the highest quality for everything. (1x will be slower but it will be much more reliable). The reason you do it slow is so that the burn is more "detailed" and will make it easier to read by a wide variety of players.
