Its not that we need space for 7616 years, its that if we only use
32 bit offsets, then we would be limited to files of 2 Gigabytes
(signed 32 bit integer) is simply not enough.

For instance, at 96kHz/24 bits, recording 8 channels would chew up
the 2Gigabytes in about 15 minutes. Some songs are longer than that,

If 32 bits is not enough, the next logical amount is 64 bits.
