i dont really know how the new single certification rule is working........ but i think its like this
Gold when it sells 500,000 tracks
Platinum when it sells 1,000,000 tracks
Double platinum when it sells 2,000,000 tracks
but since unwritten is an old song i think it follows the old rule
100k Gold
200k platinum
400k 2x
600k 3x
800k 4k
1 million 5x
1.2 million 6x
i dont know how this really is going to work
