Chill Hip-Hop Songs with Piano/Violin/Orchestra Samples?

[Javier De La Rosa]

I'm looking for CHILL hip hop music with orchestral samples/beats/hooks to play at a classy event that's coming up. I have a few songs but it's not enough to keep the playlist going long enough.
To give you all an idea of what I'm looking for, here are some links and titles:

Twista/Kanye West - Overnight Celebrity (http://www.youtube.com/watch?v=IHJcT4PP80I)
Ideal example. It's catchy, chill, and has prominent violin/piano samples.

More good examples:
Common - I Used to Love HER (http://www.youtube.com/watch?v=CM79Rr-8EIc&feature=fvst)
2Pac - I Ain't Mad at Cha (http://www.youtube.com/watch?v=d-ELnDPmI8w)
Jay-Z - Dead Presidents (http://www.youtube.com/watch?v=IIq84HQ37Dc)
(French rapper La Fouine's "Tombé Pour Elle" has the same sample featured more prominently

Paparazzi - Xzibit (http://www.youtube.com/watch?v=ocaK3Ea2sgU)

I'm looking for songs that sample this classical music style but are still chill. For example, "Say It to My Face" by Young Buck (http://www.youtube.com/watch?v=Yu1eDW8iS8I) is more lively than what I'm aiming for.

Thanks a million!

By the way -- you can also suggest lively/party Hip-Hop music if it samples orchestral music, even if my focus is on chill songs
