The phrase "what this song" is very broad and does not specify a particular song or artist. However, it could relate to:
- The song titled "This Song" by Conan Gray, released in 2025. This song's official music video and lyrics are available, and it features themes of love and personal reflection.
- A general inquiry about how to identify a song when you only know pieces like humming or a few lyrics. There are popular apps and services for this purpose, such as Shazam and Google's hum-to-search feature, which help identify songs by melody or sound.
If more details about the song are provided, such as lyrics, artist, or a tune, a more precise identification can be made. For now, "This Song" by Conan Gray is a notable recent song matching that exact phrase in the title. Would further assistance be needed on identifying a specific song or more details on how to find a song by melody or lyrics?
