So far the result of dano's suggestion produces new columns for each song. So if 15 songs you get 15 columns.
I have tried moving the loop end, putting a loop in each column, and numberous other hacks, but none work.
I had tried the loop in each col.. but didni't undertand what the marker or ref. that would allow the loop to know to retreive the formatstring from a certain song. $loop(%_filename_ext%)
As for "Sebastian Mares", You receive not because you ask not!
