Relocating can be done by pointing to the first song, provided you have moved all your music in the same "scope;" if you have made multiple folder moves, then you need to relocate by those batches, but if you simply moved the entire collection, you only need to find one song and the rest can relocate if you have selected your entire collection when using the relocate function.
