What's in a title?

When one sits down to develop their poetry or songs, shouldn't their title be true to the meaning of the song? A lot of times, even when I write sometimes, I find it very hard to remain on point. The title should mean anything, such as Juelz Santana's Song "Day's of Our Life", I think he did a great job on staying on point with that song. Not only was it a black power move in the sentiments of its lyrical meaning, but it was also uplifting.

"These are the days of our lives,
Like coke, they want us to straight drop, but we rise (hands up)
We just trying to get by, they wanna see us broke,
But they won’t, we on the grind (hands up)
They wanna see us fall, but we ball out of control,
Living above law, so fuck em all,
(I said) They wanna see us fall, but we ball out of control,
Living above law, so fuck em all (fuck em) "

That's a monumental chorus for such a song, though the actual lyrics aren't fully on task as I previously thought. I realize that his style of rap is a little more flashier, so I respect it much more when some type of positivity comes out of this. Songs like this, and Styles P "I'm Black" can definitely make the difference. Artist should have atleast one of these type of feel good songs on their album. Being the audience and also the poet/rapper I want to feel good. Now to go back to the topic, I picked this song, because the title is thoroughly represented through the lyrics and chorus. Now example of a song with no meaning, nor congruency with the actual title, We can name a few. Jay's "Snoopy Track" on Volume Three S. Carter cd, and Cam'ron's "Cookie and Apple Juice" From the crime pays album. When one reads the words or hear the song, it becomes confusing. So if your up and coming artist, just make sure your title has meaning, and you adhere to it.
