Gusta or Gustan?
Would it be correct to say, "Me gusta bailar"? or would I say "Me gustan bailar" because I am not specifying.
Gustar is one of the tricky verbs to learn because it is usually the first reverse-construction verb people run across in Spanish. So first of all, when you imagine what it means, think "pleases".
Another thing to keep in mind is that often Spanish uses infinitives where we use gerunds in English. So this is why "Reading is good = Leer es bueno."
So bailar, when used as a noun, means "dancing" and you want to say "Dancing pleases me." So it's easy to see that:
Dancing = bailar
pleases = gusta
me = me
And since bailar is a reverse-construction verb, you reverse bailar/gusta/me to a correct sentence of "Me gusta bailar."
Now if you wanted to use a plural, let's say you like dancing AND singing, or dancing and singing please you. Now we use the "they" form of gustar, which is gustan.
dancing and singing = bailar y cantar
please = gustan
me = me
So we're going to reverse bailar y cantar/gustan/me to "Me gustan bailar y cantar."
Some other examples:
Me gustan los gatos. = I like cats. (Cats please me.)
Me gustó la pelicula. = I liked the movie. (The movie pleased me.)
¿Te gustan los tacos? = Do you like tacos? (Do tacos please you?)
