One song that I truly love that I’m embarassed to admit to my friends is “sailing” by Christopher Cross. I think it’s brilliant. I sing at the top of my lungs whenever I hear it on the radio, which sadly, is rare. I do have the track on CD and get it out every now and then to listen and sing.
Yours?
Well… “Where’s Your Head At?” by Basement Jaxx is the current one. It’s such a stupid song, but I can’t help but like it.
I guess “Let’s Get Retarded” by the Black Eyed Peas would count too.
the beegees contributions to the saturday night fever soundtrack 
the month that the movie came out i was dating someone special, and it was one of the happiest times of my life, so when i get stressed out, i throw the disc in and it helps me get to sleep.
Baby Got Back by Sir Mix a Lot
I kid thee not.
“Save a Horse (Ride a Cowboy)” by Big and Rich, and “Baby Got Back” by Sir Mix-a-Lot. I love those songs with a love that I dare not speak of, except to you folks.
Uh oh. Now I gotta sing…
May Og help me, but I like Debbie Gibson’s “Electric Youth” AND “Only In My Dreams”.
I Can’t Get You Out of My Head - Kylie Minogue
Seconded for “Where’s Your Head At?”
Also… “Complicated” by Avril Lavigne. :o
I heard Britney Spears’ cover of “My Perogative” today for the first time and I liked it. I suppose that would be the current one but there’re tons of other Top 40 glurge I like that I won’t admit to anyone outside of the internet.
Tubthumper by Chumbawumba - I love that song and it always perks me up
Mambo No 5 - I can’t remember the artist but I never got tired of it even when it was waaaay overpayed.
Taht’s all off the top of my head but I’m sure there’s more…
Lou Vega (?)
I have many many guilty favourite songs.
I Touch Myself - The Divinyls
Baby Got Back - Sir Mix A Lot
Pictures and Squeeze Toy - Boomtang Boys
Frozen Puck to the Head - Captain Tractor
Hooked on a Feeling - Neil Diamond??
Convoy - CW McCall
I Don’t Want To Live On The Moon - Shawn Colvin and Ernie
any Aqua, Boomtang Boys, Prozac and a few others…
I just discovered that Big & Rich song! I like that one…
Hey you know what. I don’t feel guilty about enjoying them. 
I might not admit to some people, but that’s mainly because I dislike getting ragged on about it when some of my tastes already jive with theirs.
I don’t really have any guilty pleasure songs. I’ve burned Sevendust and Britney Spears on the same CD, with a bit of Three Doors Down thrown in for good measure. Add a dash of Incubus for variety, Tool because every CD must have Tool, and maybe some Christina or something and, bam! Great roadtrip fun. 
I care very little about what anyone else has to say about my music choices.
Daydream Believer
Sweet Caroline
I’ll have to say I love you in a song
Lou Bega.
Pretty much anything by Celine Dion.
Flutterby, have you seen the video for that Big and Rich song? It’s hilarious.
APC = TOOL
Yeah, I’ll second that one. :o
Len: “Steal My Sunshine”
For road trips, as per Silver Fire, I’d have to go with “Music at Work” by the Tragically Hip.
singing:
“Yes I like Pina Coladas,
and gettin’ caught in the rain
I’m not much into health food,
I am in to champagne”
And the theme from Ice Castles.
There are many, many more…but those two stick out (and get beaten down in shame)
