How to Pick Which 8 Seconds of Your Song to Post
Published · updated · by Loopin
You do not have to guess which part of your song works. Four candidates, two days, one number — and the answer is usually not the part you would have picked.
The four candidates, always the same four
Every song has the same four: the chorus hook, the most unusual production moment, the most quotable single line, and the transition into the chorus. Cut eight seconds of each. Do not deliberate — cut all four and let the numbers deliberate.
The reason to always use these four is that they fail differently. The chorus is the safe bet, the production moment catches producers, the quotable line catches people who never listen to lyrics, and the transition catches everyone who likes anticipation. Whichever wins tells you something about who is actually listening.
Post them one a day, same time, same format
Four days, one clip a day, at the same hour, with the same style of text hook and no other variable changed. Different posting times or different edit styles make the comparison worthless, which is how most people end up testing nothing.
Do not post them as a set or ask people to choose. A poll measures what people say they prefer; the retention graph measures what they actually did, and the two disagree more often than not.
The number to read: 3-second retention
Ignore likes, comments and even views. Open the analytics on each post and find the percentage of viewers still watching at around three seconds. That single number is what the feed uses to decide how far to push a clip, and it is the only one that transfers to the next post.
A 12-point gap between candidates is meaningful. A 3-point gap is noise — if your top two are within three points, treat them as tied and use both.
What to do with the winner
Make three more clips from the same section, changing only the visual. The section is the finding; the visual is the variable you now get to optimise. Most artists do the opposite — they keep the video idea and change the song section, which throws away the only thing they learned.
And use that section everywhere else: it is the ad creative, the release-day post, and the clip you send to anyone who asks what the song sounds like.
When all four flop
If every candidate sits under about 30% at three seconds, the problem is not the section. It is either the opening frame — nothing moving, text arriving late — or the song does not have a moment yet.
Run the four again with a fixed opening frame before concluding anything about the song. Two variables changed at once is not a test, and the opening is far cheaper to fix than the arrangement.
Frequently asked questions
Which part of my song should I clip for social media?
Test four: the chorus hook, the most unusual production moment, the most quotable line, and the transition into the chorus. Post one a day at the same time and compare retention at three seconds.
What retention rate is good for a music clip?
Compare candidates against each other rather than a fixed target. A 12-point gap at three seconds is meaningful; a 3-point gap is noise. If everything sits under about 30%, fix the opening frame before blaming the song.
Should I ask my followers which clip they prefer?
No. A poll measures what people say; retention measures what they did. The two disagree often, and only one of them predicts how the feed will treat the next post.
