The durations of tracks are given in milliseconds in column S "duration_ms". There are 1000 milliseconds in a second. If you were to listen to all the tracks on the list without stopping, how many HOURS would it take, to the nearest hour?

We need to determine how long it would take to listen to all tracks if their durations are given in milliseconds (ms).

Step 1: Convert each track length from milliseconds to seconds. Since 1000 milliseconds = 1 second, each duration in ms divided by 1000 gives the duration in seconds.

Step 2: Sum all the track durations in seconds. If you have a list, you would add up each track’s seconds value to obtain a total duration in seconds.

Step 3: Convert the total duration from seconds to hours. There are 3600 seconds in an hour, so you divide the total seconds by 3600 to get hours.

Step 4: Round to the nearest hour. After converting to hours, apply standard rounding rules to get the value to the nearest whole hour.

Notes and potential pitfalls:
- If the list is long, double-check that all durations were converted from ms to seconds before summing, to avoid unit errors.
- If you perform the division to get hours in one step, you can use total_ms / 3,600,000 directly (since 1000 ms/s × 3600 s/hour = 3,600,000 ms/hour) to get hours in one shot, then round.
- If the sums are stored or displayed as integers, ensure you’re rounding after the final division, not after partial sums, to preserve accuracy.

In practice, you would compute total_ms = sum of all duration_ms values, then hours = total_ms / 3_600_000, and finally round hours to the nearest whole number to obtain the requested answer.
