Musixmatch has a partnership with Spotify. It s growing fast because of the huge investment the company is making for Spotify and Musixmatch.
Both are focusing on bringing more data to provide an enriched audio experience globally. The lyrics feature is on the test due to the limited availability of the Spotify app in various countries.
The lack of support for lyrics in the US has offered an advantage to streaming music competitors. Due to this reason, Musixmatch and Spotify partnered to bring this feature for the listeners.
