can i play wma files from my library's audio book catalog on my mac?

[MacDoxy]

if its possible what is the best way? (and also the cheapest way)

will flip for mac or some free program allow me to download and hear the library's audio books that aren't in mac format (the pc and wma catalog is much larger) and play it on my mac?

they allow pc Mac WMA ipod(windows formatted) and mp3
but most of the catalog favors pc and wma
