Como me gustas

Como me gustas
 

¿Qué significa eso?

no context?

¡Cómo me gustas! = How I like you!

como me gustas = as I like you
As in:
¿Te gusto como me gustas? = Do you like me like I like you?

Era en una canción. Creo que era algo como "Hay 3 palabras importantes: "Cómo me gustas." ¿Qúe es la forma "gustas"?

¡Cómo me gustas! = (I like you a lot!) I feel attracted to you!

If there's a double entendre there, I don't know, but I heard the song once and it seemed to me that the character is saying that he is an emotional dry well and a hurt deer, but he feels strongly attracted to her, what may develop later. But I'm not sure of it.

I suggest you study the verb "gustar". It will make you understand it better than anything we say here... ;):)

I understand it as "How (much) I like you" or "I like you (so) much"
