New York, Dec 8 (IANS): Software developers in the US have come up with an app that turns messages into witty rap lyrics.

RapKey, a new app developed by Ativ Patel and Jonah Kaner, students of Massachusetts-based Babson College, promises to add a punch to tired texts, bostinno.com reports.

This app lets users scroll through pre-loaded lyrics, select one and auto-populate it into the text box. The lyrics are organised based on category.

For instance, in reply to a simple question like "where are you", the app offers answers like: "I'm drunk and high at the same time, drinking champagne on the airplane", or "I never sleep, cause sleep is the cousin of death".

The app works on text messages in WhatsApp, Facebook Messenger, e-mail and any programme that has a keyboard.

If the options are not good enough for the users' tastes, they can submit new lyrics that they want to see in the collection to the RapKey database.

"Rap was just a start but we would love to expand to other genres of music as well as other forms of content," Kaner was quoted as saying.
