I was under the impression that once a thread reached a certain point.....and we're well beyond it....that a "bump" on a song was tantamount to somebody dropping a quarter in the jukebox.
That may well be the case but one of the advantages of taking the slow boat as I am is that I run across songs I like and listen to them. For example, as I type this I am listening to "Fantasy" by Earth, Wind, and Fire posted in 03/11 by...you.
