I Need

Ok, so out comes Microsoft with Songsmith. It's got the world's worst commercial, but give it a break already because the YouTubes are out. of. control. A brief 101: The program allows you to sing a track before it creates backing instrumental and percussion tracks. You can tweak the styles and such but...for real, all that is not the point. The point is that people have already isolated the vocal tracks for well-known songs and synced up new backing tracks thanks to Songsmith. And it's amazing. These are some of my favorites so see for yourself:
"Eye of the Tiger"

"Enter Sandman"

"Tom Sawyer"

"Hurt"

and, of course, "Running With the Devil"

Enjoy.
