All participants in the closed beta will receive a three-month free trial of the service. To join, users need to download the TikTok Music app from the Apple App Store or Google Play Store or by visiting. TikTok says it’s inviting users in Australia, Mexico and Singapore to participate in the TikTok Music closed beta test starting today. The service includes the catalogs of major record companies, including Universal Music Group, Warner Music Group and Sony Music. The streaming service lets users sync the service to their existing TikTok accounts and listen, download and share songs. Today’s expansion comes almost two weeks after TikTok debuted the music streaming service in Brazil and Indonesia. TikTok is launching its new subscription-only music streaming service called “TikTok Music” in Australia, Mexico and Singapore.
