In that case I would suggest to just include both, the bare identifier and a
link identifying the track/album within your webservice. Using your previous
example something like:

  "@context": { ... },
  "id": "fcbcdc39-8851-4efc-a02a-ab0e13be224f",
  "title": "LAST ANGEL",
  "length": 228106,
  "releases": [
      "id": "abcd76db-7d5f-3eb7-b386-051c97bfe2e4",
      "title": "Kingdom"

Perhaps renaming "id" to something like "uuid" or "mbid". That way you would
get the best of both worlds. Legacy apps could simple extract the bare
identifier while linked data clients would be able to dereference the IRIs
in @id to get more information about specific entities. This would also
allow you to include links to the other resources you mentioned (BBC,
last.fm, etc.) if desired.
