Winamp is the only media player that will sort the playlist by path AND filename that's I've used thus far. (Will check out foobar2000.) All other media players want to sort by metadata instead and have no way to sort really old stuff that is simply a file (comes up "unknown" in the list and won't use the filename). Sorting my stuff with those shows about 30-50 unknowns. I'll stick with Winamp in Windows and Audacious in Linux. I may switch to Audacious all around if it's stable enough.
