Hello!

I am using the latest [JSON dumps|http://ftp.musicbrainz.org/pub/musicbrainz/data/json-dumps/] and finding them much more practical than the Postgres dumps (thanks!).

However, I've noticed that for some artists (but not all!) some URL relations are missing.

For instance, this artist https://musicbrainz.org/artist/270d9798-9984-49fe-b525-70e39e0ffc76/relationships has YouTube relations in MB, which properly appear in the WS/2 API, but not in the JSON dumps (but they do include YouTube relations for other artists).

At first I thought there was a limit in the number of included relations in the JSON dumps but some artists have hundreds so I'm not sure.

Is this a bug?

Thanks a lot!
