Priya Das, who describes herself as “an avid follower of world music”, wrote an awesome review of LaDiDa in India Currents this week, referring numerous times to the app’s addictive qualities

So, how does it work? LaDiDa is like singing karaoke, but in reverse. And it is utterly simple to use and to get addicted to from the get-go. Downloading it from the iTunes store is a breeze. The first aha! moment is when you figure out that the shadowy picture on screen is that of the “real” microphone in a recording studio.
You choose your style (there’s a default “E Piano Pop”). A little ticking metronome keeps beat. You hit the record button. The adrenalin does a little jig when you see the countdown “Start to sing in 4…3…2…” and you sing the first Bollywood number that comes into your head. And just like that, you’re a musician, even though the first time feels strange — who sings to a phone?
There’s like a second’s wait before you can hit play. Out floats a voice that’s yours, but with professional music backing it. It’s a feeling few of us have experienced, and oh-so-different from hearing your voicemail greeting playback, even if you may have sung it!
The second time, you try another style, say “Rhythm Synth Pop,” at say 100 BPM (it doesn’t take long to figure out that BPM stands for Beats-Per-Minute). Next, you decide to try out the Dub Tone. Then it’s time to experiment with folk with the Dirty Rap Beat set to 155 BPM. You get the picture — it’s addictive, and sure to surprise joyful mirth. Not because you’re sounding bad, but because it’s so cool.
