Not a Zune, but consider a Blackberry 9900 - there are some on eBay for around $40 [1], they take micro SD expandable storage, appear as USB drives so they don't need sync software, have a standard headphone socket, have wifi and bluetooth and touchscreen as well as physical keyboard, and the hardware and build quality is "high end business device from ~2011".

Software is nothing special, but shuffle play artist/album/song/playlist it can do.

Agreed, this was my phone for years and the speed of opening the music app and typing to filter down to what you want is fantastic. Easily swappable battery too.
