10 D songs plus 10 more
As per scrabblek8's instructions here are 10 of my favorite songs starting with the letter D in no particular order:


Dogs  -  Pink Floyd
    Probably my favorite song in high school.  I remember listening to this while reading The Jungle and working in the basket room at an indoor pool.  The room was cramped, painted black, and lit by a bare bulb.  Everything just sort of resonated. 

Darkmatter  -  Andrew Bird
    A violinist who writes great intelligent pop songs.  In this song, he starts with his childhood fascination with the game Operation and transitions into concerns about mind/body dualism and the shrinking scientific frontier.  Good stuff.

Daylight  -  Aesop Rock
    Probably his most popular song.  Aesop Rock has some of the best lyrics in hip hop.  They're incredibly dense and nearly every line is a quotable gem.  I've listened to some of his songs over 100 times and still find something new with each listen.

Deep Red Bells  -  Neko Case
    My favorite of Neko's songs.  They've even played this at the coffee shop where the Chicago scrabble meets!  If you ever get a chance to see her live, either solo or with the New Pornographers, GO!  She's phenomenal.

Devotion  -  Charizma and Peanut Butter Wolf
    Tragically, Charizma was killed in a mugging in '93 at age 19 and this album wasn't released until 2004 after Peanut Butter Wolf had founded Stones Throw Records.  This song is really catchy and it's a shame they never saw the success they deserved.

Don't Call me Whitney, Bobby  -  Islands
    These guys are goofy and fun much like their previous incarnation as The Unicorns.

The Drop  -  Viktor Vaughn
    One of Daniel Dumile's many alter egos.  He's recorded under the names Zev Love X (as part of KMD), MF Doom, Viktor Vaughn, Madvillain, Metal Fingers, DangerDoom, King Geedorah, and as part of Monster Island Czars.  This is probably one of his best songs lyrically, as he repeatedly rhymes multisyllabic phrases through multiple lines.  His live shows are a blast.

Dirty Dream Number Two  -  Belle and Sebastian
    I could probably insert Dog on Wheels or Dear Catastrophe Waitress here as well, but this song just makes me laugh.

Do This My Way  -  Blackalicious 
    Gift of Gab has fantastic delivery, and this is just a really fun song with some great, quirky lyrics.

Dial 7 (Axion of Creamy Spies)  -  Digable Planets 
    This song is on their horribly under appreciated album Blowout Comb.  To quote the chorus "Heyyyy.....  Funky"



I had a really hard time trimming down the list so here are the next 10 songs that just missed the cut:

Deep Space 9mm  -  El-P 
Deny  -  Josh Martinez
Details of the War  -  Clap Your Hands and Say Yeah
Devastation  -  The Besnard Lakes
The Devil Had a Hold of Me  -  Gillian Welch
Devil's Pie  -  D'Angelo
Did You See the Words  -  Animal Collective
Dog on Wheels  -  Belle and Sebastian
Dylsexia  -  Rob Sonic
Doomsday  -  MF Doom
