So do thousands of other songs.
> They both feature a male falsetto singer as the main melodic instrument.
No, that's not true. The lead vocal in GTGIU is falsetto throughout but BL isn't. It only has a few short falsetto phrases at the beginning. The rest is Robin Thicke's normal voice.
> The both feature a decent amount of random banter in the background.
No. The banter in BL is not random. It is very tightly orchestrated to fit in with the rest of the song, in stark contrast with GTGIU where the integration is much looser.
> The both feature the use of the chorus effect.
So do thousands of other songs.
So you hit three out of five. For any song you give me I can find you literally thousands of other songs that share three features with it.
