If you check the "upstream bug", this feature has been removed from recent versions of rhythmbox. There is a bug for adding a more general online lookup feature as a plugin instead.
I think it was gone in 0.9.3, it has definitely gone in 0.9.5 Should this bug be closed or marked as invalid/won't fix/fixed? -- automatic last.fm links don't work so well https://launchpad.net/bugs/37668 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
