What are the BEST love songs?

I'm trying to put together a slideshow of pictures and memories with my fianc�. I would like a great love song from 2007 and one from 2008 (the year we met and the year we began dating). There are sooo many options out there. I'm not very into country, but anything else I usually love! I would really appreciate any ideas to help me brainstorm, not to mention there are so many songs out there that don't get popular but are still amazing that I may not know of. Thanks so so sooo much!!
