Its like paying a guy to clean up your yard of leaves,

You can do it with a rake, and you might do a great job,

Or you can pay someone who has the correct tools for the job and know how to work them.

Unfortanetly I have seen acts like Madonna, In-Sync, who had DAT playbacks of background vocals or actually lead singing tracks.

So when you are "faking" a playback of a midi track, don't sweat it.

Brittney Spears is supposed to be a great singer and she hardly does live singing, but everybody goes to see her right?
