Are there any specific relaxing/happy songs you could reccomend to me?

Hi, I just got a[nother] mp3 player, and i wanted to put some new type of songs on it, but i cant seem to find any that i really like. Please help: I like r&b, hip hop, but the type of songs im looking for in particular is one that sounds like the same genre as "kiss me" by sixpence none the less? Please, list as many songs as you can because im having alot of trouble filling up this whole thing with songs that i would actually consider worth listening to[instead of "just another song to skip over"]. I like music that's more on the up-to-date side, please try not list anything in earlier times than the 2001, unless it's like a really really great song. also, dont just list one song [lol im really specific] because then if that gets best answer, ill only have one good song on my mp3. in a nutshell, recent songs, no rock or country, happy &/or relaxing, and please make an effort to list more than one song. Thanks! =Bri=
