Learn Spanish (Latin America): Me molesta el ruido.

With verbs like gustar and molestar, the structure is flipped. You are not doing the action; the noise (el ruido) is doing the bothering! Since el ruido is a single thing (like 'he', 'she', or 'it'), you use the 'it' form of the verb: molesta. Literally, it translates to 'The noise is annoying to me.'

What is the me doing at the beginning of the sentence?

Me tells us who is being affected by the noise. It is an indirect object pronoun that means 'to me.' With verbs like molestar, this pronoun always goes right before the conjugated verb.

Why is el ruido at the very end of the sentence?

In English, we usually put the subject first ('The noise bothers me'). In Spanish, especially with verbs like gustar or molestar, it is very common and natural to put the subject at the end. You could say El ruido me molesta, but Me molesta el ruido is the standard way native speakers say it.

Does molestar mean the same thing as the English word it looks like?

No! Molestar is a classic false friend (a word that looks like an English word but means something different). In Spanish, it simply means 'to bother' or 'to annoy' and does not carry the severe meaning of the English look-alike.
