Given a music brainz artist id (eg - Bob Dylan = 72c536dc-7137-4477-a521-567eeb840fa8 ), I can query music brainz xml web service for his/her tracks:
http://musicbrainz.org/ws/2/artist/72c536dc-7137-4477-a521-567eeb840fa8?inc=recordings
The total "count" returned is 14036. Their site says that you can use "offset" for paging: https://musicbrainz.org/doc/Development/XML_Web_Service/Version_2#Paging
Though: http://musicbrainz.org/ws/2/artist/72c536dc-7137-4477-a521-567eeb840fa8?inc=recordings&offset=100
returns the same results. Can paging be used on includes?
