Kichta is a French slang term for a wad of cash or a significant amount of money. It's a less common, more informal word than 'argent' (money) or 'espèces' (cash), making it interesting and unique.
In the song, the line "Mais si tu pars, ma kichta, elle perdure" (But if you leave, my money, it endures) suggests that while relationships may come and go, his financial stability remains. It highlights a certain resilience and perhaps a cynical view on love versus material wealth.
"HRTBRK #7" is Kaza's take on heartbreak and betrayal, told from the point of view of someone who trusted the wrong person and got burned for it.
He opens with a warning: pick who you confide in carefully, because trusting too much only leads to disappointment. From there he lays out what happened — he gave his heart to someone who "gave it back" carelessly, only to find out she was seeing someone else and coming home at strange hours.
The chorus turns the hurt into a kind of defiance: he insists he's not the one who's going to change for her, that he'll never come back, and that no matter how hard she tries, she won't forget him — he's "renting space in her head" for good.
By the end, he admits the damage is real ("my heart is destroyed, and even money can't glue it back together"), but the song's energy stays proud rather than pleading: he's moving on, scarred but unwilling to beg.
