It's just a stylistic choice. But one factor you should take into account is that the more intervening text you have between the first use of the relevant noun and the subsequent "back-reference" to it, the harder it is for the reader to parse your text. For your specific example, explicitly including it as a "placeholder" for Epic Game Music isn't particularly necessary in that respect. Include it or don't, whatever feels "reasonable" to you.
