I have many great loves in this world. Two of them include Heavy Metal and MLP: Friendship is Magic
So I basically just gave the members of the Mane 6 Metal Bands that would be their favorite based on their personalities and things they've done in the show. So I tried to narrow it down to 4 metal bands for different periods of time.
Feel free to say what you think their favorite bands should. Don't be jerks and start dissing the bands I put though. We all have different tastes. I also tried to put bands most people would know. Some of you may say man this isn't metal or that isn't metal, but it is. Just not the Metal you like. Some bands may not be considered Metal anymore after recent work, but they were.
Twilight Sparkle: Twilight is an intellectual. She is always looking for the deeper meaning of things and always trying to understand from many different points of views. So I decided to put her more on the progressive side of things:
Dream Theater, Tool, Mastodon, A Perfect Circle
Rainbow Dash: Dashie is always about being the best and the fastest! She wants to be awesome, be cool, be better. Her bands were a little easier to choose from. She doesn't quit. So I put her more on the Thrash, Speed, Metalcore side.
Iron Maiden, Megadeth, Machine Head, Hatebreed
Apple Jack: Apple Jack was a little simpler. Of course she's a country Pony who feels very strongly about her culture/roots. She also is a hard worker and layback when facing most issues. However, she does understand struggle and how hard it is to remain strong. So of course I gave her a more of a southern/groove metal sound and just a hard works pays off attitude and "nothing anyone will do will affect who she is in the heart" type feel
Metallica, Pantera, Lamb of God, Pride and Glory
Fluttershy: Her being a little more on the soft side needed a little less heavy music. Music that speaks more through more somber and tones than heavy riffs and destructive beats. Lyrics that bring out an internal thinking without being too complex. More on the Hard Rock side of things, but still heavy metal none the less.
Soundgarden, Disturbed, Chevelle, Avenged Sevenfold
Pinkie Pie: Pinkie loves having fun! Fun is what she loves! It is a serious thing for her, so even when she is being serious she will have fun doing it. Also after "testing, testing 1,2,3" it kind of stood out what she likes. I gave her bands that are more nu-metal rapping and having fun, while still giving off serious points.
System of a Down, Kittie, Slipknot, Linkin Park
Rarity: She is an artist. She wants everything to be perfect and looks for not only elegance on the outside, but on the inside, whether fierce looks and personal struggles or an absent presence with a harsh attitude. She is also about the revolution in fashion and remains up to date without losing what is in the past (can be seen in Castle Mane-ia) I gave her bands that release more consistent material and that release timeless albums or more proper sounds and majestic feeling.
Black Sabbath, Ozzy Osbourne, Converge, Nightwish
