I have many .song files of live recordings containing single (long) audio events. Within each one, I've labeled the individual songs using markers. With S1 closed, I want to search all .song files in my directory for a certain marker label. There may be 5~6 .song files containing the same marker text, but I don't know which ones. A great tool for this in Windows is dnGrep, but it doesn't work because the .song files don't use ASCII (or HEX equivalent) for marker text. Having a way to search .song files for marker text strings in the OS would be great.
