Jay-Z's 2012 "Glory" features his daughter Blue Ivy Carter's cries and coos. At less than two days old, she became the youngest ever credited artist to feature on a Billboard chart when the song debuted on R&B/Hip-Hop Songs at #74.
To the younger crowd, "A Little Less Conversation" is one of the most popular Elvis Presley songs. Peaking at #50 when it was released in 1968, it got new life in the '00s when it was used in the movies Lilo And Stitch and Ocean's Eleven.
When "Nothin' On You" reached #1 on the Hot 100, B.o.B became the first American act whose name is a palindrome to top the chart. The other two who did so prior to the Atlanta rapper were both Scandinavian groups - ABBA and A-Ha.
