1) using band names of bands that you like, spell out your name. 
Kosmos Express
All-American Rejects
Travis
Incubus
Eagles
2) have you ever had a song written about you? 
not that I know of.  Though I'd like to think that "Katie Wants a Fast One" by Steve Warner/Garth Brooks is completely about me.
3) what song(s) makes you cry? 
I have to agree with Gina.  I have never cried simply due to a song, but because of the memory/emotions it evokes.  And even then, I can't remember any songs to do so.
4) what song(s) makes you happy? 
"So Impossible" - Dashboard Confessional
"Home Life" - John Mayer
"Nobody's Fault" - Phantom Planet
"You and I Both" - Jason Mraz
"Fireworks" - Plain White T's
"The General" - Dispatch
"She Will Be Loved" - Maroon 5
"The Hardest Part of Breaking Up" - 2+Gether
"Careful" - Guster
"Good Day" - Luce
"All I Want" - matchbox twenty
"King of New York" - cast of Newsies
"Bohemian Rhapsody" - Queen
And the list goes on and on and on...
5) what do you like to listen to before bed? 
I rarely listen to music right before bed, because Sierra is usually already sleeping.  However, if I were to do so, this is what I'd listen to:
Dispatch, Howie Day, Josh Kelley, Ryan Adams, Damien Rice, John Mayer, Schinder's List soundtrack
6) who was/were your idol/s when you were younger? 
I have no idea.  Though, my musical idol who is NOT a professional musician would be my dad. 
7) first album you ever bought? 
I think the first new CD I bought with my own money was 311.
8) name some songs that remind you of people. 
"Criminal" - Fiona Apple:  Gina.  It was her code name when we were cool in the 7th/8th grade.
"Love is All Around" - Wet, Wet, Wet: Jo. When we changed the lyrics on the chair lift while skiing.  Good times.  Also, "Turn my Head" - Live.  Because of the "I can't forget you/but I can't remember" lyric.
"Even Hitler Had a Girlfriend" - Mr. T Experience:  Jake.  He told me to download it.
"If You're Gone" - matchbox twenty:  Deanna.  She loves the lyrics "there's an awful lot of breathing room, but I can hardly move".  Also, the Friends theme song and any song Phoebe sings.
"Bright Lights" & "Long Day" - matchbox twenty:  David.  He gets really into these songs.  Also, "The Game of Love" - Santana/Michelle Branch, because we made up actions to go with the song. And also, two of John Mayer's songs "Love Song for No One" and "Home Life".
"Pretty Young Thing" - Michael Jackson:  Cody.  He used this song twice to audition for American Idol.
"The Good Life" - Weezer:  Will from when he used to sing it in Driving to Milpitas.  Also, "What is and What Should Never Be" - Led Zepplin
any radiohead song:  Jason Sposeto.
Songs off the Grease soundtrack:  my crazy family.
any old Forrest Gump soundtrack-y style song [mainly from 60's and 70's]:  my dad
okay.  Done and Done.
