The TikTok Fit Score is SongScore's assessment of a track's potential for performance on TikTok, Instagram Reels, and YouTube Shorts — short-form video platforms where hook timing, energy at second zero, and shareability determine success.
TikTok's content ecosystem is fundamentally different from streaming platforms. Tracks on TikTok are typically heard in 15-to-60-second clips, not full plays. The TikTok Fit Score is calculated from: hook timing (how early in the track the most distinctive moment occurs), energy at second zero (does the track grab attention immediately or build slowly?), tempo range (120-140 BPM tracks historically overperform on TikTok), and lyrical shareability (distinctive, quotable phrases that function as content hooks).
A TikTok Fit Score above 80 indicates the track has strong organic viral potential. A score between 50 and 80 is average. A score below 50 does not mean the track is bad — it means the track is not structurally optimised for TikTok's vertical video format. Some of the most commercially successful streaming tracks score below 40 on TikTok Fit.
