The website is easy to use & we managed to find what we needed. However, initially we found it a little confusing with the different versions of backtracks of a particular track depending on the two letter designation which we found out later applied to different suppliers of each of the backtracks. It was hard to pick the one we wanted as the samples to listen to were so short and many sounded the same with such a short piece of the track. We took what we thought was the best but still not sure if we might have been better choosing another supplier! We could have taken all five versions but could have possibly wasted our time and money doing so. Keep up the good work, but maybe try and make it a little easier for a music teachers to pick the right version of backtrack for a school choir! Thank you.
