TikTok, which is owned by China’s ByteDance, recently launched a new music streaming service, TikTok Music, in Brazil and Indonesia.
Last week, the company also rolled out a beta version of the service in Singapore, Mexico and Australia.
A spokesman said it would allow users to “listen, share and download the music they have discovered on TikTok, as well as share their favourite tracks and artists with their TikTok community”.
That year, the app also said it had more than one billion active users globally.
Competition between rival social media firms – such as Instagram owner Meta and X, Mr Musk’s rebranded Twitter platform – have heated up in recent weeks.
This month, Meta’s new Threads platform went live on Apple and Android app stores in 100 countries, including the UK.
Meta boss Mark Zuckerberg later said his company’s Threads platform had signed up more than 100 million users in less than five days.
Also this week, the blue bird branding on social network Twitter was replaced by a logo featuring a white X on a black background.
The term tweets will also be changed to “x’s”, according to Mr Musk.
