I am not sure about your budget, but when I had a similar dilemma a few weeks ago, I decided to spend a bit more and eventually came up with a Denon Wi-Fi speaker. It has Bluetooth, several streaming plugins, Internet radio and even a physical audio port.

I mostly use Spotify and bluetooth for my own music collection. Spotify connect works well from within the web client. Also, the sound quality is excellent.

The price was decent, about €270.
