Should I start listening to Panic! At the Disco and My Chemical Romance?

Oh God, I just had a heart attack. YES. P!ATD I'm not a HUGE fan of, but MCR is my favorite band. Like, ever. If you're going to start listening, I'd recommend starting at the album The Black Parade, because it's hella good and everyone knows it. Then move on to Three Cheers for Sweet Revenge. That's my favorite album. Then go to Danger Days: The True Lives of the Fabulous Killjoys. Finally, if you're brave (haha) go to I Brought You My Bullets, You Brought Me Your Love. I love that album, but it's a little rough considering it's the band's first album. Oh, there's Conventional Weapons too. Eh. Oh ai wouldn't really consider P!ATD or MCR to be pop-punk, but...

Sorry for the massive fangirling! If you like FOB, you should also try Arctic Monkeys or even Paramore. Saw them both in concert and they were amazing.

Hope this helped! Go listen to MCR right now!!! (or else)...

Yes, you should! They're all awesome! :D
You should also try listening to bands like Paramore, Green Day, All Time Low, Simple Plan, Tonight Alive, We Are The In Crowd, Fearless Vampire Killers, The Downtown Fiction, Arctic Monkeys, The White Stripes, Flyleaf, The Killers, Dinosaur Pile-Up, Muse, No Doubt, The Smashing Pumpkins, Weezer, Tegan And Sara, Twenty One Pilots, The All-American Rejects, Coldplay (if you want more rock-ish music, rather than more pop-ish music, listen to Viva La Vida Or Death And All His Friends and other albums before that, or listen to all of them if you like rock, pop-rock and pop-ish music, like me :D), Evanescence, Foo Fighters, Good Charlotte, Blink-182, Linkin Park, Marilyn Manson, Motion City Soundtrack, The Used, and Two Door Cinema Club.

Although, I highly recommend Paramore, All Time Low, Green Day, Simple Plan, Tonight Alive, We Are The In Crowd, Fearless Vampire Killers, The Downtown Fiction, Arctic Monkeys, The White Stripes, Flyleaf, The Killers, Dinosaur Pile-Up, Muse, No Doubt, and MCR and P!ATD, of course. Especially MCR and P!ATD!

Good luck, and have fun listening to and discovering these awesome bands, like I did! :D

ABSOLUTELY!!! Not only are the voices and instruments amazing in both bands, but MCR has a great message, and I think that, in my opinion, FOB is always somewhat of a gateway drug if you will to those bands.

I like the album "black parade" and that one PATD song "I write sins not tragedies", so yes, also Paramore.

yes also listen to bands: two door cinema club, green day, arctic monkeys, mayday parade, vampire week end ( a few off the top of my head to get you started )

I don't listen the metal genre of music but I would recomend you listen to The Arctic monkeys, The 1975 and The Neighborhood which are slightly pop-punk I guess :)

Yea go for it there are so many great pop punk bands i personally love Panic! at the disco, my chemical romance, mayday parade, all time low(highly reccomend!!!!!), good charlotte, simple plan, ....i could go one forever but just start somewhere and you might find other bands you like :) good luck

Go ahead it is your choice, they are very good bands.

YASSS
i strongly recommend THE BLACK PARADE every song on the album is bliss. for MCR, listen to that albums and NANANA and HELENA. for PANIC AT THE DISCO, listen to THE BALLAD OF MONA LISA and DO YOU KNOW WHAT IM SEEING? Try ALL TIME LOW. they're more pop-punk and they're perfect. I recommend their latest song, SOMETHING'S GOTTA GIVE and pretty much any other song by them. (PAINT YOU WINGS, THE RECKLESS AND THE BRAVE, STELLA...)
if you get more sucked in, listen to PIERCE THE VEIL, PARAMORE, SLEEPING WITH SIRENS (older songs), BRING ME THE HORIZON..

If you want, but I wouldn't recommend it. Pop Punk gets very boring. Try some Sludge or Prog.
