i'm hooked on the custom ringtones...
i've got people set up in groups on my phone, though, so a bunch of people end up with the same ring tones.
my mom, or anyone on her side of the family - "Oceano" by Josh Groban (my mom loves his music, and got me hooked on it)
my dad, or anyone on his side of the family - "The Good, The Bad, and The Ugly" the little whistly part, because he's always been a big fan of westerns.
DH - "You and Me" by Lifehouse
my gamer friends - "Brave Sir Robin" from Monty Python and the Holy Grail
general friends - "I've Got a Lovely Bunch of Coconuts" the original version of the song the bird sings in Lion King
and then my generic ringtone is "Time to Dance" by Panic! at the Disco
i've got the ringbacks, too. just two of them, though. Teddy Geiger talks to my friends, when they call *l* and then "Sons of Marshall" plays for my brother, sister-in-law, and mom (they all graduated from Marshall University).
i try to limit myself to one new tone per month, or less... otherwise, i'd go nuts with it. *l*
