Spotify has almost become a standard to listen to online music, well above other services like Apple Music or Google Play Music. That's why loads of third-party apps have appeared trying to improve its original functions.
A music search engine for Spotify
The intention of the app Premium Music Searcher for Spotify is to improve the system to search for songs within the application. It does so by introducing the possibility to search for songs by lyrics, so you don't have to limit yourself to searching by album, song or artists.
Find music just with its lyrics.
At some point, we've all wanted to find songs based on their chorus, but we haven't been able to identify them. This app simplifies the process by showing us the possible results and allowing us to play the track straight away.
All the latter on an interface similar to Spotify that also allows us to listen to songs on YouTube and iTunes from our iPad or iPhone.
