The age thing is definitely a thing in my house. When we were both younger we both loved discovering new music. When I say "new" I mean new to us - whether it was in fact new or just older stuff we were discovering twas no difference. My future wife used to listen to stuff I'd recommend too. I used to tape her things like Eden by EBTG and now it's one of her favourites. Prior to meeting me she'd got some of the early Bowie albums out of the library, listened once, then just taped the singles! A college friend of her's told her to get them out again and give them a real listen which she did and now is a big Bowie fan. Not saying she'd like everything recommended but she'd give it a fair chance.

Now not so! Whether in the car, about the house or whatever she knows what she likes and likes what she knows and only wants to listen to that - the exception being some new pop stuff fed by the media. If she comes in and I'm playing something she doesn't recognise she'll only give it several bars before saying "what's that obscure rubbish let's put something else on". Hence we used to share discovering new sounds but now it is only myself who likes doing that. I miss sharing that experience. Especially when it is so easy now! We use Napster so find an artist you like then it recommends similar artists, their influences etc. Not to mention what can be discovered on Youtube.
