Jay is a master marketer.
He is the one who coined the idea/comparison of rappers ‘retiring’ as if it’s sports. But it doesn’t even make sense. Not only for obvious reasons but also there was only 3 years between Black Album and Kingdom Come. To put that in perspective, Nas went 3 years between It was written and I am. It only felt like such a gap bc of the hype and the very big push on going ‘corporate’ (which I’m retrospect was a good luck for the culture)
To answer your question it was a bigger deal when jay retired and we thought we’d never hear him rap again. By the time he came back, he had dropped plenty music
People have e mentioned the features, but a low key forgotten aspect is the 2nd R Kelly album

‘Unfinished Business’ dropped in 2004. It was a terrible album, but it is a full 11 song jay z album with 2 singles that were on radio.
So ultimately you had: Black album November ‘03, Unfinished Business October ‘04, features (Go Crazy, ‘05), Grammy family freestyle summer ‘06 ….November ‘06 Kingdom Come
He technically only ’missed’ 1 album cycle, ‘05.
