iTunes
iTunes is the best way to organize and enjoy the music, movies, and TV shows you already have — and shop for the ones you want to get. You can even listen to free streaming radio stations with iTunes Radio. iTunes works on Mac, PC, iPad, iPhone, iPod touch, and Apple TV.
VLC Media Player is the most popular and robust multi format, free media player available. The open source media player was publically released in 2001 by non-profit organization VideoLAN Project. VLC Media Player quickly became very popular thanks to its versatile multi-format playback capabilities. It was aided by compatibility and codec issues which rendered competitor media players like QuickTime, Windows and Real Media Player useless to many popular video and music file formats. The easy, basic UI and huge array of customization options have enforced VLC Media Player’s position at the top of the free media players.
