Oh, c'mon. Nothing is worse than kid focused "pop rock" music by a rock poser teen.
 
But with that said. Blah. No thank you again, Harmonix.

Well Harmonix, I hope your plan works and you make a lot of money from both Miley and Nickelback. 
 
That way, you can start paying for real music again.

Ugh! i would take more Miley anyday than these no talent fa--ots!

So much for Alex's story of Rock Band Network being Rock Band Nickelback, because everyone can be in, even Nickelback. Sounds like that general disdain for nickelback went away,

Wow, all the Nickelback haters. You people must have some pretty sorry taste in music if you don't enjoy theirs.

I find it ironic that Nickelback has a song called rockstar.

And Nickelback was at a time publicly bashing Guitar Hero and telling kids to go pick up a real guitar. Funny how their values have changed.

HMX is probably releasing tons of crap before RB3 comes out. Then they can start releasing better music again since it can use the RB3 engine.

Just give me my CKY please, Harmonix :(

Dude, at least Nickelbacks music sounds like guitars are being used. I never understood how they could do those Lady Gaga packs, since that music hast absolutely zero to do with real instruments. On the other hand, they´ve already screwed up with much of their DLC, so a little Miley Cyrus and Nickelback don´t exactly make it worse, right?

Man, what haters. 
 
I like Nickelback.  Maybe not my favorite band, but their songs are good to listen to.

I'll be getting Never Again, Photograph and Rockstar. Surprised they didn't go with How You Remind Me, but Never Again is my favourite song from their debut so I ain't complaining.
