Welcome to Gaia! ::

Well, I'm not a big fan of J-Pop, so I can't help you there. I'm not sure if the songs I like are to your taste, but I'll give it a shot anyway.

Death Cab for Cutie
Jets to Brazil
Ted Leo & the Pharmacists

...And if you don't have The Beatles, I pity you! (Just kidding ._.)

Those are all Indie...

Well, as of now I'm listening to Go Big Casino. I forgot they were in my iPod (hand-me-down iPod from my brother).

I also love musicals, so I have a bunch of songs from different musicals.

If you don't like them, I don't blame you XD.

Musicals = Love XD.

Avenue Q is a must <3.

As a reference to [.TwilightRain.]'s statement, get "The Internet is for Porn". It's blood brilliant. >o<

I'm not quite sure what rock/ska sounds like but I'll give it a shot, a long with some J-Pop.

BoA
Makiyo
Breaking Benjamin
American Hi-Fi
Paramore
Story of the Year
Sum 41

Case of the Mondays seem to be perfect for your taste.

If you love musicals, have you checked out the HAIR soundtrack? (Not to be confused with Hairspray, this is the one about hippies and the Vietnam war. It's got an excellent soundtrack, and you've probably heard the song "Age of Aquarius" before.)

If you like Ska... how about Sublime?

I also suggest Postal Service if you liked Death Cab for Cutie. (Same front man, before he joined DCfC.)

And, of course...
Pink Floyd and Bob Seger should always be tried.

Try these songs:
Savin' Me by Nickelback
Far Away by Nickelback

Kind of romanctic kind of songs and that's the best of their songs that aren't metal. Sorry.

Thanks to another Gaia user, I've recently gotten hooked on The Aquabats. They're a peppy-fun sort of rock band and typically dress in a superhero-costume-style blue outfit with masks and a logo (fun stuff). A lot of their songs are pretty sarcastic, and others are just plain fun. My favorites of theirs so far are "Fashion Zombies (hilarious, especially if you watch the music video on Youtube)," "Cold Raw Gold, (Might be a little heavy for you, but I love the frantic pace of it)" and "Mucho Gusto (also funny)."

If you like J-pop and J-rock, you simply have to find some X-Japan songs. It was the first Japanese rock band music I'd ever heard, and it's still my favorite. They have everything from hard songs like "Kill You" (it's literally called either that or "I'll Kill You") to slower, heart-wrenching ballads like "Crucify My Love" and "Endless Rain."

I've always loved Matchbox Twenty's music, and Rob Thomas's voice is good, too.

Genesis is a fun 80s pop-ish, maybe slightly rock band (they were around in the 70s, too, but I haven't been exposed to much of hteir older stuff). You'll probably recognize the voice of the lead singer right away. It's Phil Colins (think the Disney Tarzan and Brother Bear soundtracks or the song "In the Air Tonight"). "Invisible Touch," "I Can't Dance" and "Mama" are three of my favorites. "Mama" is definitely creepy though. Not sure if you'd like that. The other two are fun.

Another great 80s musician is Meatloaf. His singing is just awesome, and his songs are a blast. "Bat out of Hell," "Cry Over Me," and "Paradise by the Dashboard Lights" are some of his classics and my favorites.
