OK, the word "mix-tape" will do nothing for us librarians but make us look old and stodgy and irrelevant and...analog. But whether you listen to these songs on cassette, CD, or your iPod/MP3 player, Flavorwire has done the whole world a great service by compiling a list of the 10 Best Songs About Libraries and Librarians.
My personal favorite is the Nick Cave and the Bad Seeds selection, “There She Goes, My Beautiful World”. Ooops, did I just violate my professional impartiality? Who cares! It's a great song, and there are other gems and surprises on the list as well. If you have additions or subtractions to their list, check out their comments section. Interestingly, the Library Song wasn't included.
