If you have itunes or something with a search and are not sure what you want to listen to, then do this!

Choose a word, cut it up in to little 2 letter groups or something, and then enter it in to your search box.

e.g. acrobabble = ac ro ba bb le
So then only songs with those groups of letters in the title, writers etc will be on the search.

This produced the song: Glory Box by Portishead, for me! Yay. Try it with different words.
