1. Beautiful Day by U2
6. No Such Thing by John Mayer

Both right!

Missed the U2!

14 is Go Your Own Way, Fleetwood Mac

Yes!

3. I Can't Make You Love Me by Bonnie Raitt (and I can't believe I know any of them, I'm so horribly musically unaware.)

Well I'm glad you found one you knew. :)

7 is from Miss Saigon, although I don't remember the song title.

18 is Tori's The Beekeeper.

It took me a while to remember the lyrics, but the Miss Saigon song is "Please".

Wow, it's been AGES since I've listened to that. I don't even have it on my iPod, will have to do that!

It's been a while since I really listened to it, too. I find I like to listen to musical theater when I have time to really pay attention to it, whereas lately all my music-listening time is only while I'm multitasking. So it's been a while since I really listened to any of my old musical theater favorites.

Yes! (You might consider giving #10 another look. The artist has been identified but not the title.)

Oh, blah. I should know it, but I don't. I listen to some of Vienna's songs more than others. :/

That's okay. I make mix CDs for my car, and it's the songs I put on those I tend to know instinctively. So yeah, I know some more than others, too.

And now I know, 'cause I looked it up. ^^

Number 10 is by Vienna Teng um...My Love Could Keep You Alive or something like that.

Yes, but that's not the title.

Oh, and can someome explain to me what meme stands for? I feel stupid asking this but I'm just not that fluid in internet speak.

From my old friend Wikipedia:

The term Internet meme is a neologism used to describe a catchphrase or concept that spreads quickly from person to person via the Internet, much like an inside joke. The term is a reference to the concept of memes, although this concept refers to a much broader category of cultural information.

(Article: Internet meme)

A meme (pronounced /miːm/) comprises any idea or behavior that can pass from one person to another by learning or imitation. Examples include thoughts, ideas, theories, gestures, practices, fashions, habits, songs, and dances. Memes propagate themselves and can move through the cultural sociosphere in a manner similar to the contagious behavior of a virus.

Richard Dawkins coined the word "meme" as a neologism in his book The Selfish Gene (1976) to describe how one might extend evolutionary principles to explain the spread of ideas and cultural phenomena. He gave as examples melodies, catch-phrases, beliefs (notably religious belief, clothing/fashion, and the technology of building arches).

13. It Is Well With My Soul - *takes a stab* Chris Rice?

Right on the song, of course. Good guess on the artist, but no.

17 is Burlap to Cashmere, but I can't remember the title.

That's correct. It has kind of a weird title--in fact, I had to look up the lyrics to recall if the title is even in the lyrics of the song (it is, but not until pretty late into it).
