I cannot find meaning of "de más" in dictionary. Trying to translate this sentence:

What is the meaning? It is from the song of Mecano, if you need more context.
As RAE explains, "de más" generally means to be "left" or "left over", sometimes referring to an excess of something.
In the expression "estar de más", it means to "bother" or "disturb", generally used as an innuendo:

está de más = sobra. (It's unnecessary.)
