First of all, S7' s theme song "The Legend Never Dies" is a very popular one. The tune of this song is full of passion, and the lyrics also express the spirit that the legend will never go out despite failures and setbacks. Because the global finals were held in China that year, this song was also loved by many China players.
Secondly, the theme song "Rise" of S8 Global Finals was also well received. The MV of this song is closely combined with the experience of the IG team, showing an indomitable momentum. For many domestic players, this song represents their expectation and dream for the IG team to win the world championship.
Finally, the theme song "Phoenix" of S9 global finals is controversial, but its unique style and MV theme make it unique.
Generally speaking, each theme song has its unique charm and the story behind it. However, from my personal point of view, S7' s Legend Never Dies is probably the best one, because it not only has passionate tunes, but also contains the spirit of never giving up, which is also one of the core values of e-sports competition.
