i'm playing the guitar for 2 years, but i'm really stuck in my process, now.
It feels like i'm not going any further.
I take lessons, just 25 minutes a week, so i'm mostly playing by myself.

Mainly, the things i play in my lessons are easy, but i enjoy taking them, cause i got a really good teacher, but he's not so much into my music.
I tought myself fast alternate picking and tapping and i like to play metal, metalcore, deathcore, some technical things and a few death metal songs.

Right now, i don't know how to go on, i'd like to have your ideas for some songs which are fun to play and good for practicing.
Er......just any songs or metal songs?

If metal:
Iron Maiden - Hallowed By Thy Name
Slayer - Raining Blood
Black Sabbath - Sweet Leaf
Rage Aginst The Machine - Know Your Enemy
Star ****ing Hipsters - Banned From The Land

If Anything - which i recommend becuase being an 'all metal' guitarist is totally lame
Dick Dale - Miserlou (For tremolo picking, without distortion)
Bad Brains - Pay To Cum (to be able to play 5th chords ****ing fast, it may look simple but metalers usually suck at Hardcore Punk)
The Strokes - Heart In A Cage (changing from lead to rhythm quickly)
Sublime - Santeria (for playing ska, something alot of metalers fail at., the chorus is good for showing how to play lead esque rhythm)

Have fun
