Although Blynk has a Music Player widget, it’s simply an interface to allow you to send commands to a device (in this case the Arduino). The Arduino then needs to be able to take these commands and use them yo play music that is accessible to the Arduino. Obviously some additional hardware would be needed at the Arduino end, as it has no audio capabilities without this.
