I'm eclectic myself!
I always mix old w/ new when it comes to music--
just depends on my mood. ^_^
Is there a particular genre your more interested in
than others?
As for top 40 hit stuff, the newest songs I've added
lately to my mp3 player were:
Rihanna- "Only girl in the world"
Nicki Minaj- "Moment 4 life"
Ke$ha- "Blah Blah Blah"
Of course, there are bands I would listen to
whether or not the songs were 2 or 6 yrs old by now!
The Hives (Black/White, Tyrannosaurus Hives, Veni
Vidi Vicious... oh hell, they are all awesome albums!

)
The Raconteurs ( and White Stripes when I feel like
a 2-note drum beat LOL!), Serj Tankian (especially
anything off of Elect the Dead album), Franz Ferdinand,
Black Eyed Peas, and Radiohead.
You said you listen to alot of J-Pop?
One of my absolute favorite bands released an album
just last March that had mostly English songs on it.
Though its techno w/ a lil old skool Shibuya-kei
but if your into that, check out Capsule's new album Player.
Theres a DJ that made his own remix to "hello"
thats killer.
Its called "Hello (Hair Kid bootleg remix)"
you might like it, he even makes anime references
in the scat/rap.
