Thinking of You by Katy Perry (Severus Snape)
Severus Snape never got over Lily. She had been everything to him, but she left him. She left him lonely when she went after Potter. She left him alone when she died. He had begged and pleaded for it to not be true, but it had come to pass. Now, he sees those eyes everywhere he goes. He sees the woman that will always hold his soul. His only respite comes from casting his patronus, but it can never be a complete relief. He sees it there, but he cannot touch it. He steals away at nights to go to the Mirror of Erised just to see her. Each time he looks, he feels a bit of his soul die away, but it is worth it to see the one thing that never came true in real life. He sees their passionate kiss and they spend hours looking into each other eyes. Snape sobs every second he sees it, but he can't look away. And then, her son comes and he has her exact eyes. He never really looked into Harry's eyes, for fear that he would break down right in front of him. Every second he was with Harry, he thought of Lily. As he died, he finally looked at the eyes he had not truly seen in ages. They were still beautiful, still perfect...

She's Always a Woman to Me by Billy Joel (Ginny Weasley)
Harry always found Ginny to be the most unique person he had ever met. She could use her personality to make life easier, but she could also use it to devastating effects. She was fiery to the point of temper; she was tough to the point of callousness; she was kind to the point of saint-hood. At times, she could infuraite the hell out of Harry, but moments later she would make him fall in love with her all over again. Harry loved that Ginny wasn't easy to figure out. She wasn't like Cho or Hermione, who could be won over with simple acts of chivalry. You had to work for Ginny's heart, and it was incredibly endearing to Harry.

Iris by The Goo Goo Dolls (Albus Dumbledore)
Albus sometimes thought about Ariana when he layed in bed awake. He remembers the way the sun would reflect against her blonde hair, and the rosiness that settled into her cheeks whenever she laughed. He also remembers the day she came home after those boys had terrorized her. Where had his little sister gone? Every night he lays in his bed and thinks about it. Every night he feels guilty because it was he who had brought her tragic death. Albus never spoke a word about his darling Ariana. She deserved so much more than what he had given her. She was his sister; he was her murderer. Albus cried every time he thought about her... he knew no one would ever understand.

Everything You Want by Vertical Horizon (James Potter)
Everyone loved James Potter, except for the chosen few that he ensured hated him. James was everything that everyone wanted to be: attractive, care-free, and popular. He had the most beautiful girl in the world: Lily Evans. It was common knowledge that they would end up married, that they would live happily ever after. James was the asshole, though. Most of the time, people could over-look this, but it always ate at everyone. If James were a character in a movie, no one would have rooted for him. James knew this and came to accept it. He didn't bother worrying about it because it seemed foolish to want to change. He was the asshole, but everyone loved him for it.

Opheliac by Emilie Autumn (Bellatrix Lestrange) Bellatrix had always had what psychiatrists would call an "addictive personality." Not addictive in the sense that everyone loved her- no, not that by far. It was addictive in the sense that she was naturally prone to obsess. She loved to chain smoke, to drink too much, and to pour her heart and soul into seemingly trivial things. Bella loved to obsess, because it was one of the few things she was good at. She wasn't nearly as attractive as Narcissa, nor was she kind like Andromeda. So, she obsessed. And then, the true object of her love came: Voldermort. He was perfect to her and obsessing over him came naturally. And, so, she devoted everything to him and she became his ideal.

Broadway by The Goo Goo Dolls (Horace Slughorn)
Horace never really enjoyed living. He thought that, if he treated himself to the finer things in life, he would want to live. However, he was never really able to coax himself out of his melancholy. Horace didn't enjoy his famous companions, nor his perfectly-aged brandy, nor his collection of galleons. Sometimes he would sit on a ledge of a very tall building and just ponder. What if he jumped off? What if he just sat on this ledge forever? Nothing ever came of his ponderings, just a chapped ass. The only time he ever found happiness was when he saw the smile of Lily Evans. Her smile was pure, something that astounded Horace. He felt as though she were a delicate flower, much like her name attested.

Hand in My Pocket by Alanis Morissette (Luna Lovegood)
Luna loved the fact that very few things could faze her. She hated the fact that there were such things as worry and sorrow in this world. It bugged other people that she really never expressed any other emotion aside from contentment, but Luna would always smile at them. She didn't understand why people made life so difficult. Everything was so simple when you really looked at it. Be good, love others, and have fun. She knew that she was clever, but she didn't really think that it took a genius to figure it out. But, Luna didn't care. She knew that her life was wonderful and that was really all that mattered to her.
