addendum:

On some songs the vocals start up again before a solo or signature lick is finished playing, and you have to make a judgment call about whether to fade the signature part out prematurely, or risk leaving in a piece with vocals.

One workaround for that is to make a copy of the original song on yet another track, and use PGMusic's vocal remover on it. It doen't remove vocals completely, but it can provide you with a snippet at the end of the instrumental in which the vocals are obscure enough to finish the rest of the signature lick.

Just use envelopes or gain changes to bring the most desirable track forward
