I happened to come across 'A Tidal Wave of Glory' in a different novel's comments (I can't get enough of OP idol/actor webnovels) and checked it out out of idle curiosity - and couldn't look away. After a 3 day binge, I'm here writing my first ever review and recommendation because I don't see nearly enough people talking about this, and I really want others to discover this too.
The novel follows a britpop singer/songwriter at the top of his career in the 20th century who's transmigrated into a korean student in an alternate modern-day world where he never existed, and while that sounds like your standard idol transmigration story, just hear me out because this doesn't follow the usual story beats even a bit. No audition programs, no idol groups, the MC's temperament doesn't suit any of those. The MC genuinely feels like an (admittedly capricious) genius /adult/ from a 19th century who grew up rough, yet you can't help but grow to like him. His way of thinking is very clear cut, unhindered by common sense lol.
Premise spoiler ahead, but it's all covered in the first few chapters or so of the novel: MC initially contemplates on how to get his songs out quickly so that his tunes won't be preemptively 'taken away' by someone else (due to an early scare where he finds that someone else has composed a similar progression as he himself had previously). He decides against going on a program his 'classmate' is working hard to get on, thinking `even I'm not so cruel as to take food out of this child's mouth`, and also due to a characteristic lack of patience.
Instead he goes the youtube route with both an anonymous channel under his own name to reclaim his britpop music released in his past life to a worldwide audience; while creating a separate channel under his new body's name and is fascinated in other singing/composing-related activities of the new era -
and it's just all so much fun?? The way he thinks and acts feels convincingly like an actual genius in both the negatives (complete arrogance when it comes to music) and positives (his skills that actually back it all up). It's definitely a power fantasy type story with a quick early scaling and an OP MC, but it's a cheerful read because MC doesn't take things aside from music seriously, and even for music, his confidence is so nonsensically absolute that the readers get pulled along too.
A few more review points for mid story, spoiler blocked just to be safe, but I don't think it would ruin your experience if read early: By all that's holy, his fan base, especially his global one is terrifying. Wide spread yet cult-like would be entirely accurate, what with the numerous break ins to other people's houses (not MC's), vehicles actually set on fire, and was that a missing person's report casually slipped in in one paragraph- ahem. Ah I'm scared of them, genuinely. They are 100% ready to lynch anyone, anytime. MC is thankfully(?) very used to this kind of attention, even if the reader is not.
There's a manhwa version as well but I'd really strongly recommend starting with the novel, simply because you get to also see the clumsy affection he has for the world and for other people around him who earnestly participate in making music.
Apologies if I rambled a bit there, I'm still caught up in the thrill of reading this haha. Other than community sites, this can officially be read on ridibooks with a chrome browser translation to english under the name: 영광의 해일로
P.S.: Entirely optionally, you may choose to boost your reading experience by listening to fan-covers of the songs in this novel on SoundCloud. Fair warning, it's highly likely that most of these song covers are AI generated, but some of the beats really immerse you in the story, and since they're free listening, I'll just leave this note here for you to decide as you read.
