Thus, it is probably quite a good idea to post lyrics to say your feelings. The song would most likely say it better than most bloggers can. And what can better express your feeling than a sad tune to go with a sad poem? So it also makes sense to put up background music.
However, writing a song is not an easy thing to do, and when someone writes a song it probably means he has strong feelings or is very talented (take Andy Lau for example, who can write a song as an ode to the toilet bowl, AND do an MTV on it).
Enough said, I shall post the lyrics of a very popular song!
Wonderful.
