Last year a friend of mine had to sit me down and explain what ASMR was.
Knowing the kind of bubble I live in between work and writing, he was worried I was losing my touch.
I'm the first to admit I'm unable to keep up with what makes Millennials tick.
I didn't even know ASMR existed let alone that it was making noisy (and not so noisy) people rich. Mashable have an introductory video into the phenomenon in case you're not yet across it.
I ended the conversation with my friend incredulous and certain of only two things;
(i) my various career paths have all been poorly chosen 
(ii) I need to keep up with the most savvy generation earth has seen.
To that effort, I was proud when I discovered yet another Gen Y staple: reactions.
Now there are a lot of Reactions on youtube (I guess they're made by Reactors...or are they just influencers? God help me.)
In case you don't know what they are, they're basically filmed reactions to videos or moments. It goes well beyond those viral hits of people's OTT reactions to scenes from Game of Thrones that had everyone feeling things a couple of years back. Reactions have become more sophisticated and exhaustive since their Viral beginnings.
Nowadays there's a growing number of (mostly) Millennials who film their commentaries on daily pop culture, but also those who trawl back through the 80s and 90s to "discover" and "react" to classic content.
They have channels and followers, and often Stans (=major fans) make suggestions of videos or albums they should watch/listen to and then react to.
There's a fair bit of disingenuity going on in a lot of reaction videos; people pretending to watch something for the first time or reacting in a way that suggests they're doing it for the comments (or the likes or the follows).
But just like anything else on the web, for every uninformed, implausible video there's an equally honest and fascinating take on Gen X culture.
2019 is proving a huge year for looking back after all this year marks the 30th anniversary of some of the pop world's touchstones.
To my mind, Madonna's Like A Prayer was 1989's most important pop artifact.
It may've been snubbed by the Grammys, but the press today is unanimous; Like A Prayer is a masterpiece, a game changer and currently the focus of a lot of praise.
I could bang on about how for years Like A Prayer was my favourite Madonna album but we live in a Millennial world, and it's increasingly up to them to decide what from our past was significant and important.
To that end, I've rounded up some of the most insightful and entertaining reactions to Like A Prayer's ​main videos after the jump.

I hate to tip my hat to Taylor Swift, but she really was onto something.
1989 really was a watershed year for pop music.
As the months roll on this year, you'll find that your social media feeds will be brimming with 30 year anniversary posts.
​Some key albums from 1989 have had a lasting impact worldwide; others proved transformative in their local markets.
There was something about 1989 that pushed a lot of eighties acts to lift their game; to do something to justify your attention into the next decade. So many eighties pop acts seemed to come of age that year.
In Australia, as in some other countries in the colonial world, we were still coming out of a bit of a rock music haze. We certainly had lapped up the work of the international superstars, but we were a bit late to the pop party locally. 
For better or worse, genres other than rock really only started to gain traction in the mid eighties in Oz. You were more likely to find yourself down the pub watching a bunch of frizzy haired guys in acid wash making their air guitar dreams come true than you were to be having a little shuffle in the middle of a heaving dancefloor back then.
There were certainly some great Aussie pop acts that emerged in the eighties (mostly for a flash) in Australia, but for the most part we had to wait until the end of the decade for female artists to be given the space to break the rock (chick) mould.
Before then it was unheard of for a record company and the media to really get behind a local lady and really give their work the kind of attention usually reserved for the blokes.
If you have even an ounce of Australian in you, then you know that Kate Ceberano is a national treasure; a versatile singer who effottlessly jumped across jazz, pop and funk as she paved out an unorthodox career that now spans three decades.
In 1989, she released her first proper pop debut; Brave, and for a year she and her Ministry of Fun were everywhere. She achieved great commercial sucess with her solo debut.
But more importantly Kate really ushered in a new era for Australian music.
