Liveset Database, lsdb for short, is a database of DJ-mixes (not necessarily live).
Like Discogs, entities have a number and URL's have both the number and the name (which can be left out) in it.

Artists:

• regex: https://lsdb\.nl/artists/view/[0-9]+
• example: https://lsdb.nl/artists/view/40 (or https://lsdb.nl/artists/view/40/armin-van-buuren )

Sets:

• regex: https://lsdb\.nl/set/[0-9]+
• example: https://lsdb.nl/set/218501 (or https://lsdb.nl/set/218501/xtrick-ravecast-15-23-03-20 )
  I don't know where to link these too though, recordings, releases or release groups.

Tracks / recordings :

• regex: https://lsdb\.nl/track/[0-9]+
• example: https://lsdb.nl/track/442487
  On lsdb these aren't linked to the artists, only to the mixes it appears in. The artist is just in the title.

Events:

• regex: https://lsdb\.nl/events/view/[0-9]+
• these could be linked to events, places, event series and release / release group series, for example:
  • event: https://lsdb.nl/events/view/102809
  • event series: https://lsdb.nl/events/view/90912
  • release group series: https://lsdb.nl/events/view/16
  • podcast: https://lsdb.nl/events/view/91065
  • place: https://lsdb.nl/events/view/6453
