This isn't really trance, and I suppose it isn't reggae vocals either, but it might have been 'Pendulum - Tarantula'?

maybe LAROCK - Rise Up?

could be SL2 - On A Ragga Tip (Klubbheads 2008 Bootleg Mix)

Im putting my money on Habersham And Kazell Present Paradise Rockers - "One Thing" (Quivver Remix)

More progressive than trance. But still a pretty accurate match with the description. Fairly recent choon.

thanks guys for giving me some guesses but none of those were it. im trying to remember more of what is sounded like and really all i remember is the reggae vocals. almost sounded like a bob marley voice in there but im almost positive it wasnt him. Just really soft beautiful vocals. the rest of the song wasnt reggae at all from what i remember.

Maybe this one:

Arctic Monkeys - When The Sun Goes Down (Sander Van Doorn Mix)

thx but it wasnt it :"(

Probably isn't, but maybe some remix of Prodigy - Out Of Space?

thx was a good song but its not it haha

Africanism All Stars - After the Rain (Original Mix)

No wasnt it thx tho anyways
