The Glee app [iTunes link] is priced at $2.99 and with it, you can access few songs that have been featured on Glee, like “Rehab” by Amy Winehouse, and then sing along with the lyrics. You can choose to add pitch control or add pitch and auto-harmonizing, or just leave your voice as is.
Then you can sing along with the Glee voices. Your performance is recorded and you can then choose to share the tune with your Facebook friends or with other people in the Smuleverse. You can also record and share your own a cappella tracks.
For those of you who don’t watch the show, Glee uses the story of a high school glee club as the format for a modern-day musical filled with lots of recognizable pop songs, so making a musical iPhone app for the show makes a lot of sense.
You can Watch Glee episodes online.
There are three songs included for the $3 price: “Rehab”, “Somebody to Love”, and “You Keep Me Hanging On”. “Can’t Fight This Feeling”, “Imagine”, “I’ll Stand By You”, “Lean On Me”, and “No Air” are each available for a $1 each.
I expect Smule to bring out a similar Karoake app for iPhones and iPads not restricted to Glee, but with many more songs.
