(FYI, I hold different views than this instance)
TL;DR: for me it's current russian warsongs and covers of 80-90s classics that put the opposite meaning into them. Polina Gagarina, Shaman are the most known artists due to being banned from YT, but there are dozens of them. What and why - I'd try to explain in following paragraphs.
They don't feel either inspired or honest, most of the worthy artists don't want that mark in their resume so it's left either for newbie artists or oldies who fear they are losing relevance. The western-in-everything 'Π― ΡΡΡΡΠΊΠΈΠΉ' is the only catchy tune local media empires could produce, others are even more cringe like '333', they don't even compare to what repressed guys did and do.
Surprisingly, the same notion is shared with my relatives who do support the war (unlike me) or at least our men there. We still have a tradition of singing along the songs of old over the table when we meet with our elders, or over the fire if camping or meeting in the countryside, mostly soviet songs with inclusion of 90-00s. And itso happens there's none of the promoted ones in the menu.
But that also tracks with the concerts on the TV we sometimes put on. It's all older stuff by mostly aging artists. The contemporary russian music culture, as I suppose, was castrated by some sort of negative selection and I can't think otherwise.
And what is really embarassing for me personally to hear is appropriation of songs that are either anti-war or asking for changes (namely KINO's ones) sang in this day and this year by those who support both the regime and the war on state TV. That's like this one republican guy just one hair width from discovering what RatM's songs are about. There's some second-hand shame you want to wash off in a bathroom right after hearing.
