I found a song on a lyrics site that seems to have the same lyrics as Giulia's new song but I'm not 100% convinced it's actually Giulia's new song.
Some of the lyrics match a song called 'Your House' by Levi Batkin, but none of the lyrics I found include the 'You know the bassline, yes?' section, which is definitely sung/rapped by the same person who does the 'You gotta get into this lyrical flow' section.
There are three possible scenarios here:
1) Giulia's new song is the song I found, and the lyric site simply doesn't have all the lyrics
2) Giulia's new song samples the song I found, and the lyric site doesn't have all the lyrics
3) Giulia's new song and the song I found both use the same vocal stems from a sample pack, and the song I found has been constructed around those acapella vocal stems
I think it's most likely to be the third option. Levi Batkin seems to be a producer for hire, making cash here and there with soundalike beats and music for media production. I've done work like this myself, using royalty free sample packs either to give context to instrumentals, or using those acapellas as the basis for a new song entirely.
Either way, the Levi Batkin song has been completely scrubbed from the internet so there's no way of checking it.
My next step is to look up vocal sample packs to see if I can find the acapellas. I'll keep you updated.
