Dont know the first track but the trippin' track is most probably Goldtrix feat' Andrea brown - Trippin'
There are four mixes, Original, different gear, tillman uhrmacher and the vinyl b side mix. Tillman uhrmacher mix is available in the tracks section of this site.

Goldtrix......made up of some producer with name daniel (i think) goldstein and matrix aka jamie quinn.....known for his drum n bass productions with his brother aka optical and the singer is andrea brown.......sister of us soul legend kathy brown. She did a tape for goldtrix uses a jill scott song....the producers liked it so much....they made with the vocals.

And the 1st track u mention, is possibly

Jakatta - Ever so Lonely.
