What song has the first stanza lyrics 'i got a feeling' it's from the 90's or 80's?

The song you're thinking of is likely "I Gotta Feeling" by The Black Eyed Peas, but it was released in 2009, not the 80s or 90s. If you're looking for a song from the 80s or 90s with similar lyrics, you may be misremembering. There are other songs with the phrase "I got a feeling," but none from that era match exactly. If you have more details, I can help identify the song better!
