Soon I’ll have the courage
To leave my thoughts behind
I’ll give back all the knowledge
And keep the wisdom precious in my mind

Massive Attack (1994)

Release API

Release length

The minimum is 179.5 seconds, which rounds up to 180 seconds, which is 3 minutes. A pathological example is here:

<track id="b9346c0a-1166-30e7-aba3-997ef3065abd">
   <position>4</position>
   <number>4</number>
   <length>179600</length>
   <recording id="0393ce29-889d-4e9a-930e-c110bb87626d">
      <title>In Our Angelhood</title>
      <length>179600</length>
   </recording>
</track>

measured by the millisecond, this track is too short. Measured by the second, this track is long enough. Listed here at 2:59:

To resolve this, we need to round to the second before making any decisions.
