Because it helps fans find you. What if they hear your song in a friends car but forget to ask the name of the group or it's on the radio and it isn't announced? What if they see you at a small venue or opening for a larger band but miss your group name there? Well, if they like your songs they will probably remember a line or two and if you've got your lyrics posted somewhere online you've got a chance that they'll find you! I recommend indilean.com because there's no spammy ads or spyware like some other sites, second it is permissions based meaning everything that's posted is adhering to copyright laws, and third I provide three links for bands to use on each song page to help them promote their music.
