Well ....
Blake, being the old fart that he is, has a tendency to listen to ... old stuff.

As in, he shows a preference for listening to The Who, Genesis, and Yes. All Brit groups, naturally.

Songs in particular that he has a tendency to listen to, include:
Home by the Sea and
Just a Job to Do (Genesis), and Who Are You (The Who).
Like I said, he's an old fart, and he says that Shaun can stop groaning in disgust now. XD
Tom also has a tendency to listen to Yes ... in particular
Leave It (which also seems to fit him, somewhat)
Other than that, I'm still getting acquainted with Tom and his musical tastes. >.>
Jonas ... well, these days, he's more inclined to listen to Peter Gabriel, in particular
Burn You Up, Burn You Down. Yeah, it's another fairly old song, but I think it describes his trials and tribulations of the past year rather well. (In case you're wondering, it was a song originally featured in a video game called Uru: Ages Beyond Myst. Yes, I am a fan of Myst. >.> )
Now, as for my girls ...
What can I say, Megan's ... well, a depressed dufus. Sort of. She has a tendency to listen to The Fray and The Script these days. I believe her main theme song is
Over My Head (Cable Car) ... it really does sum her up rather well.
Susan doesn't want to go out about her musical preferences ... so I'll just keep mum on that for now. XD
(however ... she's the only charrie of mine with a chronological playlist of her life in general. >.> And when it's just her and Kellen, she has a tendency to listen to Simple Minds and Texas--both Glasgow-based rock/pop groups, go figure--and her theme song would likely be Wild Mountain Thyme by the Silencers, another Scottish band. She would swear up and down that Texas was looking at her life when they recorded their songs. And she also listens to Caipercaille a lot; they're a Scottish folk group that has a tendency to record half their stuff in Gaelic. She ... just doesn't listen to this when Shaun's around.)
