iTune Hiccups

When you hear a song and it keeps playing in your head for the rest of the day. Sometimes several days

I heard "Ditty" by Paperboy on the way to work. I have the worst case of iTune Hiccups

Itunering

Catching tuna using an app.

Also: an old man's terrible guess of the anagram "RNGIEINUT" which is clearly RINGTUNE.

Sorry I can't attend this very important and worthwhile meeting, I'm out itunering.
