First ones that came to my mind (all original studio versions):
- The 7/8 bass riff from Rush's "Tom Sawyer"
- The bassline under the guitar solo from Rush's "Limelight"
- The bassline under the first verse of Beatles' "With A Little Help From My Friends"
- That ultra-groovy fill near the end of Beatles' "Everybody's Got Something To Hide Except Me And My Monkey"
- The final section of Beatles' "You Never Give Me Your Money" ("1, 2, 3, 4, 5, 6, 7, all good children go to heaven")
- The middle section from Jaco Pastorius' "Come On, Come Over"
- The bass riff from Mick Karn's "Tribal Dawn"
- The bassline under the main guitar riff from Kiss' "Cold Gin"
- The intro from Black Sabbath's "War Pigs"

My ringtone!
I'm sure there are more, but those are the ones I can recall right now.
