Newer music tends to get looked down upon for no reason.
They get looked down upon because people don't look at the newer better bands.
They get OVERLOOKED for no reason.
People say newer music is crappy because music is evolving, and people for some reason don't like bands that adapt and change to a new era of music.
I will help you change your mind by giving you a few newer rock bands.
Foster the People. (best song Helena Beat) Yes, they are good. They are mainstream but that doesn't deny that they are a good band.
Alabama Shakes (best song Don't Wanna Fight) Relatively unknown, I think you'll like this a lot!
MGMT (Electric Feel) Quite popular, same reason people don't like them is the same as Foster the People, new era of music and people don't like it.
Arctic Monkeys (whole entire AM album) Post-Britpop songs heavy influence from Oasis and Blur, what's not to like?
The Black Keys (Howlin' For You) Blues Rock with an old music mixed with modern sound mix. Again looked down because they are adapting and experimenting for no reason.
The Fray (How to Save a Life) Melodic song.
Hozier (his whole debut album) Mainstream artist therefore disliked despite incredible voice.
Imagine Dragon (Warrior) Come on, same reason mainstream artist so everybody dislikes them. They have a great guitar rift, but of course they'll say that they stole those (how do people even steal the idea of guitar rift anyways) from older bands such as The Who and what not.
Muse (Time is Running Out) Probably the most unique and revolutionary of all the bands I've listed so far..
Phoenix (Listzomania) Upbeat music... disliked because they are, i don't know..., too upbeat?
Ratatat (Loud Pipes) Very unique duo artist. I don't think any music comes close to what they make because it's just that unique. Too bad unique is bad and nobody likes unique eh?
The Strokes ... no comment on this they're great.
Sufjan Stevens (Death with Dignity) How can you hate this song...?
Sia (Chandelier) Again.. you can't really hate this song. Depressing. Great Voice.
Mark Ronson (Uptown Funk) Overplayed song but you can't hate this 80s disco song..
Adele in general gets undeserved hate however she's a great singer.
Lykke Li (Youth Knows No Pain) Check her out.
Beck is still putting out great new musics. His album Morning Phase deserves more publicity than it gets.
Tanlines has a good album called Highlights.
In general what I'm trying to say is that all the good new musics get overlooked for no reason. People focus on all the crappy music such as the rubbish of One Direction and Jonas Brothers instead of focusing on the better music of the modern days.
HOWEVER
All the classic bands such as The Who, The Clash, Beatles, Zeppelin, U2, Oasis, Sex Pistols, RHCP, Radiohead, The Doors, etc.. I love them all still.
