I've watched a few episodes of the Voice and I've heard them say:
- this song is in the pocket
- you're in the pocket
- you need to find the pocket
Is this just something they made up like when Randy Jackson used to say "you can blow" to mean "you are a good singer" or is "in the pocket" a real musical term?
I've heard the term before in a variety of ways. One of which being playing in one position and another being playing only chord notes when harmonizing.
It's definitely not a classical music term or anything.
