If you live in a fairly large metropolitan area, you will find many routers for sale at cheap price. I got an Orbi router plus mesh satellite unit for $150.
Music streaming usually uses the UPnP protocol. For it to work well, you want to turn "IGMP snooping" off in the router settings. Orbi lets you do this; the TP-Link routers I've seen do not give you the setting and do not document whether the firmware has it on or off.
