Slow scanning thumbs hangs on scanning

I have 3000 songs scanned them on 2 iPads from a synology has observed, the scan will hang after about a few hundred where I have to restart, took 6 hours to scan, and sometimes I play a song off the nas it will hang and not load about every fifth song, the speed control is useless should add a pitch instead, interface good like iOS 8 good replacement as iOS 9 music interface not that great, recommend holding off purchase till these bugs are worked out.
