Yes, popular songs are generally getting shorter, and part of that is due to platforms like TikTok and streaming services driving the change. According to Billboard, TikTok and streaming “fragmentary moments” favour shorter tracks. The Washington Times reported that many artists are adapting to algorithms by trimming intros or making songs around the 2½-3 minute mark. However, it isn’t only TikTok: analyses say the trend also reflects changes in songwriting, listener habits, and how streaming counts are measured. So the claim is broadly correct: songs are shorter and TikTok plays a role, but it isn’t the sole cause.
