Well the common denominator is that YOU are playing those basslines. Maybe what you hear is your playing style.
However, it doesn't hurt to expand your vocabulary. Listen analytically to other genres to get new ideas to incorporate in your playing and copy the basslines you hear. The bass teacher I had a few years back once forced me to learn one song from Standing In The Shadows Of Motown (I'm Gonna Make You Love Me), and from that song only I got plenty of new ideas about rhythmic phrasing and note selection. I highly recommend that book. Nothing wrong to take influences from a bassist as great as Jamerson was.
