LOTR references in songs?

Does anyone have the link to that list of bands that have LOTR references in their songs? I saw this a few months back and can't remember where. The only one I can remember is Led Zepplin, and even then I can't remember the name of the song[s].

That Led Zep song was Ramble On.

Rush has a song named Rivendell, which is obviously LOTR-inspired.

The metal band ""Blind Guardian"" dedicated one of their albums to Tolkien.
The album is named ""Nightfall in Middle Earth"" and is really GREAT if you like metal. I love the song called ""Noldor"". Great stuff. They''re similar to Angra or perhaps some Iron Maiden.
