this is very good observation I can confirm, in 90s we watched with my sister music videos and radio stations since tapes were quite expensive and CDs came later (and never really took off with me, almost everything pirated), so we listened almost everythjing in radio in 90s and watched music charts weekly even in TV to stay in picture. though to be honest you could still be specialized, for instance I was quite a lot into EDM and you could listen almost every day (at least in Europe through 90s, especially in middle 90s) at least 1-2 hours just purely EDM shows, don't really remember other shows with focus on other genres by end of 90s internet grew a lot, Winamp and MP3 were introduced plus songs through Napster, Direct Connect and I quickly turned away from radio and TV for most of my content and focused almost entirely on soundtracks while still listening to radio in work, still feel kinda nostalgic when thinking about our military dorm in beginning of 00s when we were listening every night in beds ballads like Hero from Iglesias to fall asleep by the end of 00s I was either travelling or started to work in places without radio in background, so my knowledge of popular music after that dropped pretty much to 0, now you could play me anything from 2010< and unless it's megahits like Gangnam style I would have no clue whether it's popular unless I heard in shops or restaurants when passing by (and since I was out of western world for most of 10s part, good luck with western/US hits) chart from article should clearly state it's American and I would like to see comparison between different continents, especially which western music would be recognizable in Asia, only then you know it's true global megahit of course all of this is my personal observation and I'm sure it's also age thing with people having less time to listen the music and less focus on it as they age
