MUSIC

I want to know if it is normal for me not to be interested in music. I love listening to music and hearing good beats but I just don't get it when people can memorize a whole song and love lyrics so much. I just like listening to good dance music. I'm a teenager by the way. Does this make me weird or less involved in the world. I'm more interested in movies actually. I'm not an outgoing person and I'm kinda shy most the times unless I'm talking about something I'm interested in such as movies. I wonder if thats part of the reason why I'm not so involved in "new" music.
