guitarmageddon,
If you follow the posts here, you will see that there are both. Not sure what kind of music you are into, but right off hand, POD GOD has a few in his file list that have Vocals. "Green River", "Funk 49", just to name a couple.
Some people don't want vocals, because they like to play the guitar parts AND sing. Others, like myself, don't sing well, so I don't put vocals on, but I have.
Just look around, BT's with Vocals are here
I've looked everywhere and then I found this place. These people are great, the re-creations are EXCELLENT and if you don't find what you are looking for, post a request in the "Request Forum" and specify you would also like vocals.
Enjoy! This place is awesome
