"Don't Know if It Works Only 1st 30 Seconds of Song Demo"
I don't know if there are any pros.
The developers of this software do themselves a disservice by only removing the first 30 seconds of vocals in the demo version. Few songs have any lyrics at all during that lead-in. I have no idea if this works.
Buyer beware. If you can't test it out, I wouldn't risk buying it.
