| 10 | * <h3>4.16. Play counter</h3> |
| 11 | * <p/> |
| 12 | * <p> This is simply a counter of the number of times a file has been<br> |
| 13 | * <p/> |
| 14 | * played. The value is increased by one every time the file begins to<br> play. There may |
| 15 | * only be one "PCNT" frame in each tag. When the<br> counter reaches all one's, one byte is |
| 16 | * inserted in front of the<br> counter thus making the counter eight bits bigger. The counter |
| 17 | * must<br> |
| 18 | * <p/> |
| 19 | * be at least 32-bits long to begin with.</p> |
| 20 | * <p/> |
