MyBook Live Duo to MacBook Pro - very slow music streaming

Hello, have you tried to transfer a big file to see the transfer rate that is currently possible? If you are using an Ethernet adapter it could be the reason for the slow transfer rate. If possible try connecting the Live Duo directly to a PC/Mac with an Ethernet port to see if you get a better performance. 

When transferring large files to or from a Personal Cloud drive, performance may be slower than expected
