I tried using Strawberry a couple years ago. It suffered from a bug where every so often, playback just stops.

(Another bug was that the album art Strawberry displays is a severely downscaled, and then enlarged-with-obvious-pixelation, version of the art embedded in the file. It would be easier, and look better, to just display the embedded art.)

Shortly after I reported this, they decided they wanted to turn into a paid service.

I was not left with a very positive impression.
