TikTok shapes new musical trends because its short viral video format allows users to quickly discover catchy songs. Thanks to challenges and massive sharing, some music becomes popular very quickly, thus influencing charts and listening habits.
TikTok uses a recommendation algorithm based on users' interests and behaviors: what you like, watch until the end, share, or scroll past quickly determines what will be suggested to you next. Instead of being limited to your close friends or the influencers you follow, your feed quickly becomes highly personalized, showing you pieces of music that are completely unknown or emerging. The result: thousands of people discover the same new songs simultaneously, allowing them to gain incredible popularity within a few days. Thanks to this viral mechanism, TikTok regularly turns simple music tracks into true international hits.
TikTok mainly relies on very short video formats, usually between 15 seconds and one minute. This brevity encourages the use of short music clips, carefully selected with catchy parts: a catchy chorus, funny lyrics, or a particularly striking rhythm. As a result, the tracks are often repetitive, which promotes easy and quick memorization. When users watch videos featuring the same music clip repeatedly, this repetitive aspect quickly becomes viral – the track stays in their mind and naturally encourages them to participate by creating their own video. This phenomenon leads to the massive emergence of ultra-popular songs in just a few days.
TikTok challenges, those little video tasks that everyone starts recreating, are true drivers for launching songs. A single catchy chorus is enough to create a trend: users make the track their own, create their own version of the challenge, and very quickly, it spreads. By becoming the soundtrack for a viral challenge, a song immediately gains visibility and sees its number of streams skyrocket. Ultimately, these participatory challenges and viral trends significantly boost popularity and sometimes turn unknown tracks into genuine global hits within just a few days or weeks.
Highly followed creators on TikTok have become true music influencers. When a popular influencer uses a song, their millions of followers are quickly exposed to that track, often for the first time. These personalities propel unknown songs to success simply through their appeal and authenticity with their audience. When a famous user starts a dance or trend to a specific song, their fans imitate it, creating a snowball effect that accelerates the spread of the track across the platform. Artists who were previously under the radar suddenly gain fame thanks to the simple musical choice of one influential person.
On TikTok, you don't need to be a professional or expert to create or remix music. The app provides users with very simple tools to easily integrate a song into a video, modify its excerpt, or combine it with other sounds. Thanks to this simplicity, anyone can transform an existing track, add their personal touch, and create something completely new. This democratization of remixing encourages creativity and leads to remixed tracks quickly being widely adopted and shared. The result: sometimes unexpected songs suddenly become popular with a large audience, simply because many users adapted them in their own way.
In 2020, nearly 70 songs that gained popularity on TikTok subsequently appeared in the US Billboard Top 100, thus demonstrating TikTok's strong influence on the current music industry.
Lil Nas X's song "Old Town Road" initially went viral thanks to TikTok before becoming the longest-running number one on the Billboard Hot 100 chart (19 consecutive weeks at the top).
According to a study conducted in 2021 by MRC Data, 67% of TikTok users report being more likely to search for a song they discovered on the platform, confirming the social network's key role in music discovery.
TikTok claims a global active community of over one billion monthly users in 2021, making it one of the most effective platforms currently for quickly propelling a song to global trend status.
TikTok directly impacts official music charts by amplifying the visibility and listening of certain tracks. When a song goes viral on TikTok through challenges or trends, it often leads to a significant increase in streams on platforms like Spotify or Apple Music, thereby changing the official charts.
Yes, record labels actively use TikTok as an essential marketing tool. They often collaborate with popular creators, launch specific challenges, or encourage remixing to boost the visibility of new artists to a wide audience.
Some old songs become popular on TikTok thanks to the spontaneous creation of challenges or trends around these tracks. The nostalgic effect or the catchy aspect of a melody can generate viral excitement, making these titles reappear on the charts despite their age.
Indirectly, yes. When a song goes viral on TikTok, the renewed interest usually leads to a significant increase in streams and downloads on streaming platforms. Thus, even though TikTok itself does not directly pay artists for each use, the popularity on the app generates additional revenue through increased external listens.
Short, catchy music with an easily identifiable section (such as a chorus or a catchy melody) is particularly suited for TikTok. Songs with clear lyrics or a rhythm that allows for simple choreography are also more likely to go viral, as the app favors quick and repetitive interactions.
It is difficult to predict with certainty the exact emergence of musical trends, even though some indicators exist. For example, the impact of highly influential creators, the catchy nature or humor associated with a song, as well as the ease of creating playful or participatory content increase the chances of a piece of music becoming a viral trend.
