USB is the best thing since vinyl
Dunno about you lot, but I have gotten well sick of supposedly eternal CDs becoming scratched and unusable after a week or two of hard handling in the car, mostly by the kids. I've had to make copies of every CD I bought and use that for the few weeks that it might last. The result has been stacks of useless silver disks all over the place or fast-forwarding to find a non-skipping track.
Recently I bought a new car stereo with an SD slot, a USB port and an AUX jack, and life has become so much simpler. I bought a 1GB key for each of the 3 sprogs and leave them to put whatever they want on them - and no more burning of entire CDs just to add one song to the playlists. No more CDs in fact. They take turns with the keys, or plug their mp3 players into the USB port or the AUX jack, and control it all by the remote.
Everything that I want to hear, well OK, that they DON'T want to hear, is on my own key.
And the entire collection is stored in the hitherto-defunct ashtray!
The player will also rip from CD to USB so I only need to play a new CD once on the way home from buying it...
And if 1GB isn't enough space for them? Tough, they can delete something that they probably never listened to anyway.
As for vinyl, I'm still playing albums that were pressed over 30 years ago.
