Metal=throw on some Kalmah or Children of Bodom. Speed/Thrash metal with harsh vocals and quite a few of the songs range about 200 bpm. Just cut it in half.
Great energy and fast fast playing with a happy/heavy sound and great riffs and solos that doesn't make you want to slit your wrists when it's over. It's not pure anger and rage. It's perfect for keeping the drive and motivation going.
Think Megadeth with way more heavy/uplifting/catchy riffs each song, amazing guitar play, and screaming death metal style.
