Dude, that mixtape is a lame crybaby pussy-man mix, you need some good hard songs about fucking to round it out, although this probably says more about my distaste for RnB 'love' songs than it does your mixmaking skills. Every V-day I make a tape for my lady and I can consistently make her cry, which is a victory for me.
EDIT: You can't start with the Whitney, that's like a premature cumshot, save that shit for later on when the mix heats up. Also, two Leona songs in a row? No, pick one or t'other, not both. // EDIT AGAIN: use Angel I think, A Moment... is a bit lame IMO "Woah I can't believe this is happening to me!!" Umm, no, unless you're refering to the early ejactuation with the Whitney? :lol // Two songs one after another is a big no-no - here are my rules:
First, only one song per artist (this rule can be broken once-per-mix but the songs must at least be from different albums). For a lovemix I like to start off strong with some classic low-key romance, take it up a notch with some more pace and then once again with a bit of lovin', and then hit below the belt with a sappy softie that'll melt her heart. You can put a couple of softies together, and then at around the halfway point start with the songs about fucking. Very important. Pace the tape like you're seducing her - melt her heart, take her clothes off then fuck her hard, then hit up with some post-coital cuddles, then back to the bedroom. Also, use some songs that you love but she doesn't know. If they're especially good she will connect these songs to you and they'll be all the more special. I use B-sides for this purpose usually.
Here is my most successful (IMO) mix, it's a bit rock oriented for your tastes most likely but it did the trick for me -
Peggy Lee - Fly me to the moon (classic original version - pure romance - represents her) This might work for you
I'm From Barcelona - Treehouse (a song that represents me "I have built a treehouse, it's a you and me house")
Adem - Spirals (soppy song using spinning galaxies as a metaphor for two lovers)
Bright Eyes - First day of my life (classic indie love song, makes her cry on cue) This might work for you too, I dunno
Broken Social Scene - Swimmers (sexy voice, sets the mood)
CSS - Let's make love and listen to death from above ("Wine then bed then more then again")
Green Day - Hitchin a ride (leftfield, but it's a song she saw me perform with my band when we first met)
Morning Wood - Take off Your Clothes (raunchy song about gettin nekkid)
Groop Dogdrill - best sex in Texas (groinal groove rocker, such a sexy song)
Postal Service - Brand New Colony (electro romance, nice pacing to bring it down after the fucking)
Frank Turner - You are my Sunshine (the kick in the balls/uterus, so sad and romantic, tears guaranteed)
Fester - Fuck (a song by my mate's band - "I'm bored I'm bored I'm bored lets fuck!", always gets a laugh after the heart on the sleeve sappyness of the previous tracks)
Hmm, that was fun to write... as for you mix, no idea mate, got any Lionel Ritchie going on there? How about some Stevie Wonder?
