It doesn't take any qualification to say "I like this group", because you like whatever you want, that's freedom. But before telling what is good rock and what is real rock, you need to be able to compare. And for that... well, you need to listen to rock !
AC/DC, Motorhead, jimi Hendrix, Nirvana, Elvis Presley, The who, The White Stripes, Iggy Pop, the Pixies, The Sex pistols, The Strokes, System of a down, to name a very few. To be clear, I'm pretty sure you didn't listen to or didn't like real and good rock, because if we reason in term of real rock, it's a pretty shitty band you are showing us.
