Why a #1 in Pop is supposed to be as rare as a #1 in Rock
Lock a genre and the reel changes. The chart result should not get easier just because you picked the juicier shelf.
People notice fast that Pop feels denser than Hip-Hop or Rock. More spins land in the high 80s. That is not in their head. In this catalog Pop really does have more songs sitting up top. If chart position were just average rating with no translation, Pop would spit out #1s and the other filters would feel like chores.
I did not want that. A filter should change which catalogs matter and how hard it is to spread artists. It should not quietly make one mode easier.
The unfair version
Early on, genre modes used the same strength-to-chart mapping as All Genres. Raw strength is your twelve picks blended together before they become a debut. Pop sits higher, so the same skill produced better chart outcomes. Hip-Hop and Rock players were not worse. Their shelf just had a thinner high end.
You can call that "realistic" if you want. Some genres have more globally enormous songs. You cannot call it a fair mode. Modes are how you want to play. Not secret difficulty settings.
What I did instead
I did not nerf Pop song ratings. Lying about individual tracks to balance modes would wreck Classic and every All Genres run. Ratings stay tied to the evidence. Each genre gets its own translation from raw strength onto the shared chart scale.
I measured that with a pile of simulated drafts. Millions per genre per mode, random play through near-perfect greedy drafting. At each skill level I recorded what raw strength that behaviour produced in Hip-Hop, Pop, Rock, and All Genres. Then I built anchors so a competent Pop draft and a competent Rock draft land in about the same chart neighbourhood, and a true #1 stays about equally rare.
Pop still feels dense while you draft. The song numbers are real. The end-screen projection is the part that gets translated.
When you are playing
Hunting a personal-best chart position? All Genres still has every top-rated track. Filters are for how the run feels, not for farming easier #1s.
If you lock Pop and your songs look stronger than last week's Rock run, that can be true and still produce a similar debut. A 92 average in Pop is not automatically "better play" than an 88 in Rock. That is the point of the calibration.
Classic and Expert have separate tables. Expert's deep-cut nudge and hidden ratings change how people draft, so copying Classic's curve would have been wrong.
What I am not saying
I am not saying the three catalogs are equally "good music." I am not saying every spin inside a filter is fair. And I am not settling biggest vs greatest. That fight is over here.
I am saying picking Hip-Hop, Pop, or Rock should not be a hidden difficulty slider. Genre guides cover how each pool drafts. This note is why the end-screen ranks stay comparable when you switch.
