It is easy to find the name of a song by looking through its lyrics. In many cases you can find information online through various search engines but if you don't have access to one of these engines you should consider looking carefully into the lyrics of the song.
There are a variety of different places to go to online for finding song titles. The Zworks website at zworks.com offers assistance where users can enter in the first or second phrase from a song in order to get information on a song. For instance, if you type in "born to be down" in the "Phrase from song" box you'll find that those are the first lyrics to Local H's "Bound for the Floor," a song that doesn't even refer to its title in its lyrics.
Songlyrics.com provides information on lyrics too. To find a song title from its lyrics just go to the "Advanced Search" section. If you type in "fight to get it back again" into the site's search on that section you'll find that those lyrics come from Pearl Jam's "the Fixer."
In the event that you can't get to any of these sites here are some tips that you can use for finding out the name of a song when you are listening to it on the radio or at a restaurant and you get no information on the song. A good way to find a song title when looking into the lyrics is to consider the chorus. In many cases a musician will put an emphasis on certain words in a chorus. These words are ones that can be louder or clearer than others and in many cases can come at the beginning of a song. A good example of this would be the Beatles' "Hard Day's Night" in that the title is the first thing uttered in the chorus and that line comes in clearer than other lines.
In many cases a band can repeat some phrase multiple times in a song. This can be a sign that the phrase that is being repeated is the name of the song. The Eagles' "Life in the Fast Lane" is a good example in that the title is repeated within other lines in the chorus.
Don't forget though that in many cases the words in the chorus may not contain the actual song's name. After all, not every chorus is going to overtly repeat the song title over and over again in the chorus like with the songs by the late outsider musician Wesley Willis.
If a certain lyric or song title is repeated many times in the verses or is used as an important part of the lyrics throughout the song then it could be the title. Sugar Ray's "Someday" is an example in that the song title is used as the first word in many verses in that song.
