My "favorite" songs number in the thousands in different languages, three of which I understand, and two (Italian and Spanish) because I love the melodies. Besame Mucho, anyone?
I like songs much more than classical music and, if I like the melody, will track down the lyrics to see what it means. On a cruise ship, I once heard a Filipino pianist playing a tune in a lounge. Recently, I thought of tracking it down, reckoning that it must be a popular song in the Phillipines, and was successful. Yes, the Web and youtube make it much easier now.
As another example, I like to listen to Paul Mauriat's Orchestra, which is like the Boston Pop Orchestra of France (though most Americans would think of it as "elevator music"). One of the albums had the song "Un monde avec toi" (A world with you). As the melody and the song title sounded so romantic, I tracked down and listened to the singer and the lyrics.
It is only recently that I learned that the Canadian singer, Raymond Berthiaume, who recorded the song was not the original singer.
It was Frank Sinatra and the song "The world we knew". I listened to the musical score first, then the French version of the song before getting to the original and well-known crooner!
