The line 都不甘于平庸 seems to be speaking of a degree of confidence, and a will to demonstrate it.
But the lines before and after it, don't seem to support this interpretation.
How is it best to read this line?
The relevant lines are below.
恋恋不舍又念念不忘
被汹涌浪潮淹没
覆盖了属于我
最孤独的海洋
迷茫的 游荡
不知去往何方
支离破碎
或遍体鳞伤
研磨成匆匆过往
一幕幕的相逢
都不甘于平庸
原谅我 此番
不经意的设防
跌跌宕宕
你占据我的遐想
封上你路过的窗
你的声音
来来往往
穿梭在无人演出的剧场
