I voted for six:
LWTSH
Slow Dancing(original version)
HMTMKMKM
Two Shots
Holy Joe(for the Garage Mix)
Sweetest Thing
Just to be clear, we're talking about the Extended Dance Mix of LWTSH, right?
Assuming we are, I voted for it because it's beautiful, and the last half of it is one of the most dreamlike three minutes U2 has ever put on record imo.
The original Slow Dancing is just a simple, beautiful, country-ish ballad. I love the chorus - "slow dancing, slow-oh-oh dancing, she took me slow-oh, oh-oh, dancing all night long".
HMTMKMKM is a monster.
The Garage Mix of Holy Joe is just really enjoyable, fun rock song. The part where Bono screams 'all mixed up in everybody's life, closer than ever to everybody's wife' is a line that's really fun to sing along to imo. The whole song is.
I think Two Shots Of Happy, One Shot Of Sad might be one of the best songs Bono ever wrote. It would send perfectly at home being sung by Tony Bennett or Frank Sinatra(for whom it was written) or any other jazz/standard singer. Love, love, love it.
Sweetest Thing is catchy as hell and is one of the most effortless pop songs U2 has ever put out, imo. It's really got that JT magic. I've always loved the 98 version too, even if it is much more syrupy than the original(which I also love).
