Lyrics. 

The words to a song, in another words, lyrics brings meaning to the music. Imagine a song without lyrics. It can get a little bit boring. Lyrics bring the meaning to the song and the lyrics tells you the genre of the song. Simple. 

Sometimes you would need lyrics to quote your feelings and situations, but the problem is you don't really know what are the lyrics. That's the big problem. 

No worries, Winter would help. Simply comment the song you need lyrics for below and I'll post it up here.
