List of obscure recordings that have many Acoustids linked to them, most/all of the links were invalid. They seem to fall into two groups, either duration is not set, or track title is a funny one likely to match many things or a combination of both
I think if we could add the duration to those recordings in the list missing them that may prevent this problem reoccurring, but I struggled to find the duration of the ones I checked, perhaps someone else could have a look ?
