I find myself constantly listening to this soundtrack. Hitch was a funny & upbeat movie, and so is the soundtrack. It features Amerie, John Legend, Omarion, and some great old school sounds by the elements Earth Wind & Fire, The Temptations, and the O'Jays. A lot of the more contemporary songs on the album are remakes (like John Legend's, and Omarion's) but even they are great.
Amerie - One Thing: Generally, I'm not a fan of Amerie, but this is such a fun song to listen to. The vocals aren't exactly top notch, but this is a great track to dance to.
John Lengend - Don't You Worry Bout a Thang: A great remake of a Stevie Wonder classic. Though John Legend is no Stevie, he does an AMAZING job covering the track.
The Temptations - I Can't Get Next to You: I'm sure you've all heard this one.
Mark Ronson - Ooh Wee: Another fun track. Features Ghostface Killah & the classic Nate Dogg. This again samples an older song ; but this is still a fun song to listen to.
This is a soundtrack that you can really listen to from beginning to end without skipping. I suggest you pick it up.
