It is cross-platform—indeed, one of its pleasant selling points used to be that (on Macs only, I think) it could play FairPlay-DRM'd files just by piggybacking on the libraries that iTunes used to do the same. However, as ahstilde (https://news.ycombinator.com/item?id=11680232 https://news.ycombinator.com/item?id=11680232) points out, it is officially discontinued as of 2013. The Wikipedia page https://en.wikipedia.org/wiki/Songbird_%28software%29 https://en.wikipedia.org/wiki/Songbird_%28software%29 has a nice summary, including a link http://sourceforge.net/projects/songbird.mirror http://sourceforge.net/projects/songbird.mirror to the Sourceforge page, and to a "community-supported fork" http://sourceforge.net/projects/ngale http://sourceforge.net/projects/ngale (which I have never tried).
