I'm trying to set a song's duration in microdata format. What is the best way to describe a duration in microdata?

Is it by using itemprop="duration" in span?

<span itemprop="duration" content="PT4M5S">4:05</span>

Or using the time tag?

<time itemprop="duration" datetime="PT4M5S">4:05</time>

Or using the meta description?

<meta itemprop="duration" content="PT4M5S"/>4:05

Or a combination of all of them?

<span itemprop="duration" content="PT4M5S">
    <time itemprop="duration" datetime="PT4M5S">
        <meta itemprop="duration" content="PT4M5S"/>4:05
    </time>
</span>

I tried and they all worked in google's Structured Data Testing Tool except for the last one where the result was a three durations!
