So, I am seeking a good digital playback program for my PC. Is there one out there that supports all media file extensions (.mp3, .mp4, .wma, .flac, .nrg, etc.), combined with a very intuitive and easy to use library/ playlist creator? I really like iTunes, but it is very limited in what file types it suports. Winamp supports alot of file types, but its library/playlist creator sucks. What would you recomend?
