I'm going to start off with The Beatles. Oldies Indie (is that what it is?)? Amazing. My most favorite song by them is "Elenor Rigby". But then I saw Across the Universe and immediately fell in love with "Girl", "Hey Jude", and "Hold Me Tight". Love them.
But then there's your screamo bands. I love A Day to Remember -- their songs "All I Want", "If it Means a lot to You", and "Downfall of Us All". Then another favorite is Black Veil Brides -- love their songs "Perfect Weapon" and "Never Give In". And then there's Screamo-Techno. Breathe Carolina anyone? Love their songs "Rescue" and "I'm Not the Kind of Guy to Take Things Personal". Also, there's Eyes Set to Kill -- "Come Home", "Darling", "Beauty through Broken Glass", "March of the Dead", and "The World Outside".
And now what about Pop...let's see....Selena Gomez -- "Who Says", "Love You Like a Love Song", and "Ghost of You". The there's Hilary Duff (I will always love her music). My favorite songs sung by her are "With Love", "Fly", "So Yesterday", "Coming Clean", "Stranger", "Weird", "Inner Strength", "James Dean", and "Someone's Watching Over Me".
Then there's the Alternative and other-type-of-genre bands such as VersaEmerge ("Past Praying For", "Fire (Aim Your Arrows High)"...)
I somehow tend to fall in love with some Christian songs. Like "The Last Night" by Skillet, "Hanging On" by Britt Nicole...
