Somehow these songs remind me of the lost song:
The song I'm looking for is a bit more uplifting, and the lyrics are very uplifting too, maybe about feeling good or partying, putting your hands up?
(Not summer jam!)
The song was really popular some years ago, although I'm not sure how long ago! I'm guessing about the same time as summer jam? 2004 or something.
Somehow the song also reminds me of bob marley but it's absolutely not reggae, just house/dance with a touch of reggae.
