Lisasolomon,
Let me see if I am getting this right.
You want someone to send a sample of a vocal reduced song?
You not only want a sample sent to you but you want sample of specific songs!
You’re asking someone to send you a 30MB plus file attachment so you can decide IF it’s good enough for your 11 year old daughter.
First, the quality of a vocal eliminated song has a lot to do in the way the song was originally mixed. Most new songs are very difficult to process for a number of reason, some of which, you can read by clicking on this link:

Second. I think you would be a lot happier IF you bought the software, then you can try as many songs as you’d like, I am you will get a good number of usable tracks.
Third. The software is only $54.95; after all, it’s for your daughter.
I don’t mean to be critical. I just think this is your best solution.
Good luck,
Jon
