- Q: what are some good pump up songs? i prefer metal?
- Not in my opinion.
- Q: ROck (metal rock ) Vs Hip hop, rap ?
- Ahhh ... some must fall by the wayside, including the Sons of Odin. Paul Stanley and Viincent 'Alice Cooper' Furnier advance, for mine.
- Q: My dad is a sheet metal worker. My brother told me he is a metal fabricator. Are they the same thing? Or just similar?
- A mecha specializing in nuclear warfare, invulnerable to currently existing weapons. Only known way is Stinger missles in weak spots, and Solid Snake.
- Q: Whats the best metal and hard rock music that is newer?
- heavy Metal is a form of music originating in blues-based hard rock, and acid rock. It involves a hard beat, loudness, distortion, and a massive amount of POWER. Thats what metal si to me. Metal has to sound powerful. From 30BPM drone metal to massive thrash beats, ti all sounds powerful. The only exception really is gothic metal, which really doesnt have much aesthetic similarities to normal metal. Also, to be considered metal, it has to have a direct descent from classic heavy metal. for example, although Black metal doesnt sound much like classic metal, its real metal because it came directly from other forms of metal. unlike, say, Nu-metal, which features vast influences from alt-rock and rap. Also, metal DOES NOT have to eb fast. I have to point that out.
- Q: I enjoy power metal and their artists. Artists like: Blind Guardian, NightWish, Iced Earth, HammerFall, and many more. So, anyone a power metal fan out there as much as i do.
- I'm pretty sure Candlemass are doom metal.

- Q: they have some heavy riffs and the sound of them is very abbrassive but something keeps telling me that they're not really metal. what do you think?
- I keep asking people why they hate nu-metal and honestly nobody can give me a straight up answer other then theyre jumping on the hate nu-metal band wagon. Heres a list of bands Korn Limp Bizkit Disturbed Linkin Park Mudvayne Sevendust Coal Chamber Dry Kill Logic SOiL Flaw Stained Primer 55 The Deadlights Motorgrater Kittie Papa Roach The Deftones And alot more hard rock/metal bands from 97-02.
- Q: Apart from the facts that metals always loose electrons and are good electric conductors and that non-metals always gain electrons and are bad conductors, what is the difference between the two?
- Metals have a very low specific heat, which means that it takes very little heat to change their temperature. This means two things: Metals heat up quickly, and metals cool down quickly. When metal is in the direct sunlight for even a short period of time, it heats up fast. For example, the buckle on your seatbelt. However, metal is also quick to cool down. The air in your room probably is blowing across the metal and in this way the metal is constantly in contact with a colder mass, and heat can quickly move out of the metal.
