Selectatrack is usually quick and easy to use once you have an account and the selection of songs is very good. Quite hard sometimes to know which version of a song is the right one to choose, because the segment you hear is not the part you really want to hear or is too short, but this must be difficult to overcome without giving the whole song away, so I understand it. I did get one song from recent purchase which was actually not a backing track but seemed to have someone singing on it - Hold back the river - it is the first time it has happened, but still not sure why?
