Some songs converted propertly….others didnt…songs would list actual legnth of song in iTunes but then only play for a second or two, giving a little chirp and then moving to next song. Bought another program for 1/2 the price (FLACtunes FLAC converter) and everything worked fine. Tried to find tech support prior to purchasing new software but didnt seem to be available on web site (or was impossible to find if it was). The interface is absolutely gorgeous and simple and intuitive to use…just didnt convert properly.
