Ha! I noticed the new music thing too. My music supply has almost completely stagnated.
Personally, I hate not having a car. You should definitely try it out, and if you like it, go you! If you hate it, you’ll have extra appreciation for going back to a car lifestyle when you get another. I know that whenever I’m in a car these days (rare, but it happens), I feel so special and privileged…like someone who’s been on a desert island for a year, getting to spend a night at the Hilton and eat a steak dinner. But I digress. 
My reasons for being a hater:
–I have to go shopping ALL the TIME. I can only carry so much stuff home with me, and poor husband is clueless. (I have to spell it all out, otherwise he’ll come home from the grocery with either a single loaf of bread or a bunch of random stuff that doesn’t equal a meal.) Or have everything delivered. Having everything delivered is either expensive or unreliable, as I’m never home during the day and we have no doorman.
–No quick trips. My dad once called me and told me to send a birthday card to may aunt. I had to make a 50-minute trip, walking several blocks down the street and back, just to find a place that would sell me a card. And I don’t have the space to stockpile cards in my apartment. And public trans, even though fairly reliable, means putting my destiny in someone else’s control. Train stuck ahead of me? Hope I’ve got a good book, it’s going to be a long afternoon in this tunnel.
–Speaking of public trans, I’ve had it up to here. Maybe I’m really prissy or something, but I can only take so many smelly people rubbing themselves up against me while I fight for hand space on a disgusting, sweaty metal pole in this life. Someday, I’m going to start screaming and crumple into the fetal position until the guys in uniforms come for me.
–Family far away. I can rent a car or fly to see them, but I feel so dependent. They have to shuttle me back and forth to the airport or car rental place (usually the airport anyway) and it’s expensive either way. And I can’t take a trip on a whim.
All things to think about. But you really should try out going carless for a while. You can always go back. And I have tons of friends who love it and think 'm crazy.
Fortunately, I’m leaving NYC in a couple of months. And getting a car!
