Taeyeon's newest song, "Nights Into Days," is receiving much praise from online users.

On February 2, Taeyeon released the second single, "Nights Into Days," which is part of Naul's 'Ballad Pop City' project.

After the track was revealed, many netizens praised Taeyeon for changing the way she sings. 

Netizens wrote in online communities, "Taeyeon used to have a nasal singing style, but she has since completely transformed her vocal technique," "She sounds the way when she debuted," "I love it," "I love this song," "She really took out that nasal sound from her singing," "She had rhinolalia, so she had no choice," "The way she sings is the same as 'Can You Hear Me...' and 'If' like a long time ago," and "I love it so much that I have this song on repeat."

Taeyeon recently revealed, "I'm a perfectionist when I work on an album and Naul is just a perfectionist as I am. I am actually thankful that he gave me the chance to sing (this song). We also have a similar style."

Meanwhile, Taeyeon has been receiving much love on the tvN entertainment program 'Amazing Saturday - Doremi Market,' and has made special appearances on MBC's 'I Live Alone.'
