As an example of what MrC is talking about I just converted a MC 17 csv (comma delimited) export to be identical to MC 16 txt export (pipe delimited) in a matter of seconds in Notepad++
I was curious as to the format difference and it is just the pipes vs commas and the MC 16 format has some extra delimiters (see below)
MC 16|Name|Artist|Album|Track #|Length|File Type|
|Helpless|Metallica|The $5.98 E.P. Garage Days Re-Revisited|1|6:36|flac|
|The Small Hours|Metallica|The $5.98 E.P. Garage Days Re-Revisited|2|6:40|flac|
MC 17Name,Artist,Album,Track #,Length,File Type
Helpless,Metallica,The $5.98 E.P. Garage Days Re-Revisited,1,6:36,flac
The Small Hours,Metallica,The $5.98 E.P. Garage Days Re-Revisited,2,6:40,flac
Just as an FYI the playlist in question had 1420 files in it.
