在角落唱沙哑的歌在大声也是为了你
[zài jiăo luò chàng shā yā de gē zài dà shēng yĕ shì wéi le nĭ]
Suggests performing heartfelt yet hoarse songs in isolation but also doing so loudly because of the intended listener – indicating deep emotion conveyed through song, especially love music, performed passionately even if unnoticed by many.
