It is an app which currently takes in lyrics and gives the name of the song with the name of artist, album and lyrics.
With that user also gets to see some songs by that artist and more songs in that album.
Well it's not all APIs, some coding is done apart from that to extract full lyrics and song covers.
Maybe you will like the UI. Swipe feature in the found song is also awesome try that.
Speech to text doesn't work for now. I need someone to fix that.
