SoundTalk is a lightweight text-to-playlist utility that is capable of generating playlists on Spotify. If you happen to come across a conversation that contains an artist and song, SoundTalk will match them up, and you can start listening immediately. It's very easy to use. The app's primary function is to take text that can be used as a song name, and match it with a Spotify playlist or artist's name. This is accomplished using a regular expression, which is a very powerful and versatile tool that allows you to match patterns and even capture groups.
