In 12*11*10*9*8*7*6*5*4*3 = 239500800 ways.
It is the product of 10 consecutive integer numbers, starting from 12 in descending order.
1-st record to play can be any one of 12 records;
2-nd record to play can be any one of remaining 11 records;
3-rd record to play can be any one of remaining 10 records;

. . . and so on . . .
The last, 10-th record to play can be any one of remaining 3 records.
