I decided to quit after going thru the A's in my collection... I actually pulled up a few thousand songs when I put in "Love" as the keyword, although sometimes this is because the word is actually a part of the artist's name or in the case of the Beatles, some of their songs were remade for their
Love album and so the song in my collection has "(Love album version)" appended to the title. If a song title is repeated in the list above, it is because it is a completely different song with the same title -- not a cover performed by a different group / artist.
[EDIT] I was thinking of the song "Unforgettable" where they created a duet version of Nat King Cole and his daughter Natalie. After re-listening to the song "L-O-V-E" I realized my error, and also that Nat's version is the best.
