Learn Spanish (Spain): Le gusta la música de España.

The verb gustar works a bit differently than 'to like' in English. Instead of 'She likes the music', Spanish phrasing is closer to 'The music is pleasing to her.' The word le is an indirect object pronoun that means 'to her' (or 'to him').

How do we know le means 'she' and not 'he'?

By itself, we actually don't! Le can mean 'to him', 'to her', or 'to you (formal)'. We only know it means 'she' here because of the English translation or from the context of a conversation. If you need to be specific, you can add A ella at the start: A ella le gusta la música de España.

Why is the verb gusta and not a different form?

With gustar, the verb changes to match the thing that is pleasing, not the person. Because la música (the music) is singular, we use the singular form gusta. If she liked multiple things, like songs (las canciones), it would be gustan.

Do I always need the la before música?

Yes! In English we can just say 'music' when talking about it in general, but Spanish requires the definite article (el, la, los, las) when a general concept or category is the subject of the sentence.
