I have been stuck with these regular picking exercises for about a year now (playing with a metronome) and I'm so damn tired of it, I'm wondering if there is any good songs to learn to help you get the alternate picking going, ive been playing for like 6 years know, so I'm open for any suggestions, Just can't take more from that metronome ^^

try the gargoyle or the curse of castle dragon by paul gilbert. that should take you a couple days to get

Yeah, try paul gilbert for some shredding.
If that's not your kind you could also try playing the mid solos from Metallica songs (if you like their music) like the first 2 "One" and "The Unforgiven" solos. Another good one could be "Master of Puppets" solo interlude. I know those ones are not to fast, yet good.
Technical Difficulties by Paul Gilbert is a good one. The sticky has a list of stuff by technique (for example: songs that improve sweeping, songs that improve tapping, and so on). Your pick.
