johnstevensaul did this first I saw, but as he often does, he's started a trend.

Step 1: Put your MP3 player on random.
Step 2: Post the first line(s) of the first 20 songs that play, no matter how embarrassing the song.
Step 3: Post and let everyone you know guess what song and artist the lines come from.
Step 4: Strike out the songs when someone guesses correctly.
Step 5: NO CHEATING (that goes for the guesser, too!)

1. And the meek shall inherit the earth 2112, Rush -- nemo_wistar
   
2. (instrumental)
   
3. Virtue is relative at best
   
4. What the hell is wrong with you tonight? Different for Girls, Joe Jackson -- quodlibetic
   
5. Ninety-nine point nine Fahrenheit degrees Suzanne Vega, 99.9°F -- celaeno
   
6. When I woke up this morning I felt a pang
   
7. Welcome to my country, welcome to my home
   
8. Love, love, love, love is a weird thing
   
9. (undecipherable)
   
10. It's getting better all the time The Beatles, "Getting Better" -- origamislayer
    
11. The old bastard left his ties and his suit Ben Folds, "Bastard" -- crescentdude
    
12. When we wore a heart of stone, we wandered to the sea
    
13. (instrumental)
    
14. You should have listened what your mother said
    
15. When your love's flown out the window
    
16. Sometimes I think he knows too much
    
17. Brick by brick, stone by stone
    
18. Yes, it's true I want that apple
    
19. My doctor told me that it was time for me to have my X-ray Crash Test Dummies, "Here I Stand Before Me" crescentdude
    
20. Now I lay me down not to sleep Barenaked Ladies, "Who Needs Sleep?" -- crescentdude
    

BTW, good luck with 2, 9, and 13. The guess you're likely to make for 9 is wrong. I'll give you another hint on 9 -- the whole song's lyrics are basically undecipherable.
