This is like magic. When you have a folder is named "ABC" and inside that folder your 10 tracks each is named as "01.dsf, 02.dsf, 03.dsf, 04.dsf......10.dsf". It was impossible to tag those audio file except doing it manually (**IF** you know what those are). But now with MAN301, it can be done automatically. Amazing and unique feature. Here is first example: 1 - Under Storage -> Select folder/files -> Edit Tag 2 - Bottom section can view all these files carry empty metadata 3 - Click ">" to fetch Gracenote for matching metadata 4 - Apply - > Wa La! All metadata are fetched from Gracenote, including the wonderful album artwork!
