It seems like you might be trying to say:
"Sos la canta esta muy loca"
This translates to "You are the song, this is very crazy" in English.
However, it's not a common or natural way to express this idea in Spanish. The sentence structure and meaning are confusing.
To get a more accurate translation, it would be helpful to know the context of the phrase.
For example:
* Are you trying to say someone is singing very enthusiastically?
* Are you trying to say someone is singing a crazy song?
Please provide more context so I can give you a better translation.
