The claim is that popular songs are getting shorter because of TikTok, which is partly true but oversimplified. Research shows that it has become shorter on average over the last decade, but this trend started before TikTok. Platforms like TikTok have accelerated the change by rewording quick hooks and catchy segments that work well in short-form videos. TikTok is definitely one reason why songs are shorter, but not the sole reason. According to BBC, shorter songs are partly driven by streaming economics, and artists now design songs with instantly catchy intros to capture attention for people to use a portion of it for TikTok. Their data shows that, " the average Billboard Hot 100 song length fell from 4:12 in 1990 to about 3:00 in 2020". A stream counts after 30 seconds. This encourages quick hooks and reduces incentives for long intros/long songs. TikTok’s own report may emphasize its cultural influence to promote the platform, which is a potential corporate bias. Journalism sources like Billboard or BBC are more neutral but still reflect an industry-centered perspective that values reality and streaming success. TikTok’s format rewards short, catchy clips, which directly influence artists to make songs that are concise and hook-driven. Many viral hits like Olivia Rodrigo’s “Good 4 U” gained attention first through short TikTok clips, showing how song length and structure are shaped by the platform’s viral culture. Data from Quartz and PRS for Music show that song length had already been declining for years before TikTok existed, due to streaming behaviors and algorithmic playlisting. This means TikTok did influence but the trend, but did not create it. The cause is more complex, combining technology, audience behavior, and the economic design of streaming services. The claim is partly true that songs are shorter today, yet the trend began with streaming platforms, and TikTok simply accelerated it by rewarding brief, catchy hooks.
