The only two Apple software for Windows have been the first to embrace the new features offered by Windows 7 in its Superbar. Safari 4 shows tabs as separate Superbar thumbnails that can be previewed & closed like Internet Explorer 8 & with iTunes 9, Apple has brought in quick-play controls to the Superbar preview like Windows Media Player 12 and also has Jumplists.

It is interesting that neither Mozilla nor Opera who have released major versions have adopted Superbar’s capabilities. Chrome 3 final build supporst JumpLists. And honestly, beside iTunes & WMP, I don’t use any other media player (VLC is a just-in-case.)
