From official Saints Row 2 blog;
Quite a few people know about the hidden Achievement in Saints Row 2 called “Soprano”, with the description of “Sung along to the radio”. The best part of the description for the achievement, is that I had heard many cases of individuals actually singing into their headset to try to get the achievement to unlock, which is pretty hilarious.
For those that figured it out, to unlock the achievement, you need to be listening to 107.7 The Mix, and if a few specific songs play when you are customized with one of the six voice options, your in-game character will start to sing along to the song. Yes, we actually had all six of our main voice actors record themselves singing along to some of the greatest 80’s hits of all time. The easiest way to get the achievement is to listen to “Take On Me” by A-Ha, since all six of the voice actors have that specific song, plus one of their own.
Today I received a private message to our VolitionTube account which had the following video attached, and it’s pretty amazing. He actually took the time to stitch together all 6 voice recordings and create the symphony below. It truly is a work of art.
