Apple is in talks to buy the popular song recognition app Shazam as the tech giant tries to compete with streaming leader Spotify, TechCrunch reported Friday.

The technology news site, quoting unnamed sources, said that the deal could be announced Monday with financial terms not yet clear.

A spokeswoman for Apple declined comment.

Since its founding in 1999, Shazam has offered a high-tech solution to listeners' longtime agony over not recognizing music on the radio or in bars, letting users identify songs through their phones' microphones.

Shazam, which is based in London, said last year that it had reached one billion downloads on smartphones.

But it only recently started to see profitability by incorporating advertisements and tying up with other tech firms including Spotify and Apple, to which it refers traffic.

It would remain to be seen how Apple would integrate Shazam, which also faces competitors such as SoundHound.

Apple, which earlier revolutionized online music with iTunes, in 2015 launched Apple Music as the market turns to streaming, which offers unlimited on-demand listening.

Apple said in September that the service had more than 30 million subscribers — a rapid rise but still trailing industry leader Spotify which said it had 60 million paying users as of July and 80 million more on its free tier.

Stockholm-based Spotify earlier Friday announced that it and China's Tencent were taking minority stakes in each other -- a likely sign of Spotify's growth ambitions in the world's most populous country, where it is not yet present.
