Upgrade my DAC or buy more weed?

I was a regular pot smoker in high school and college, and found that my life would always take a down turn while I was smoking regularly.  I believe this is because I was too young to use it responsibly and allowed it to take over my life.
I'm in my 50's now and find that I can use it responsibly and that it enhances my enjoyment of life in some ways.  I no longer smoke it, ever since I discovered edibles.  Gummies are my favorite.  I find edibles very relaxing as they seem to provide a body buzz more than a cerebral buzz (but also have enough of the cerebral buzz to be enjoyable).  
I only eat once a week on average, and this frequency keeps me on track to remain responsible in other areas such as family commitments, work and social life.  I have chronic pain in my lower back and joints.  I find weed helps with this, but I do not take it for that as I do not want to use it daily.  
I find that my enjoyment of music greatly increases when I'm high, similar to what the OP describes.  I don't fully understand why this is, but I think it's because the weed relaxes muscles and slows the brain function just enough to allow the music to process in the brain at a deeper level.  No everyone experiences this with weed.  Several of my friends are fascinated to hear that music sounds better to me when I'm high.  

Pass the Twinkies!

As THC becomes legal in evermore states (and ultimately on the Federal level), I think we need a "THC users group" thread so seasoned uses can advise newbees and share experiences. Fortune has made THC (not using street names on purpose) available to me after 35 years of non-use and it was worth the wait (has pluses and minuses of course). Someone here recently described THC and music as "a match made in Heaven". I agree.

Weed, music, and FOOD!  There's your match made in heaven.

Two weeks ago I had a work buddy over for some smoking and listening, something we do every few months together.  He bought me a great gift of some very fine bourbon:  Blanton's Straight from the Barrel.  I started loving bourbon ~3 years ago, and I find it a perfect accompaniment to weed.  This Blanton's has re-defined what bourbon can be to me.  It is ridiculously expensive, so you only pour a little, and you sip it really slowly.  I literally will simply wet my tongue with 3 - 4 drops and let is soak in - - it's a 5 minute experience per application!  It just evolves in so many wonderfully flavorful ways over that time, so much more than any other bourbon I've drank (Prichard's Double Barreled and Colonel Taylor Single Barrel had been my previous "bests").

Well, while having smoked some fantastic weed and enjoying an ounce or so of this Blanton's, I started applying this same long, slow savoring approach to the food we had:  outstanding licorice, chocolates, seasoned nuts.  And I found that the Blanton's had changed my life.  I ended up eating only a little bit of food throughout the 5 hour listening session, as opposed to getting stuffed to the gills.  This solves my biggest problem with weed:  the munchy monster.  And it is just so much more "zen".

I do think weed changes how your brain reacts to sensory perception, which makes tastes and sounds just so appealing (and physical intimacy, it must be said - - tough to beat sex!).

Like @snackeyp above, I was a real chronic for a few years in my adolescence, and I found steady smoking to be deadening to life.  But at a frequency of once a week max, I find weed to add something nice.

I also find weed to be an excellent differentiator for system quality:  if my system is tending to the boring or annoying side, I just can't stand it stoned.  If I'm leaving the room, that speaks volume about where my system evolution is at.  When I have it tuned right for "engaging" I never want to stop listening.

I was listening to some old tunes last night and had a temporal shift back to some meaningful events in my life that were current when I was listening to this music.

Listening to Overnight Sensation and Apostrophe last night took me back to the 420 Club in Amsterdam a few years ago, where a huge photo of FZ was staring down at me from the wall while they had his albums playing, while I watched a video on a huge tv screen with no sound from a nature show of the release and flight of a Condor with a Go Pro strapped to his back, while I waited for the joint’s (pun intended) Volcano to do its magic.  Indelibly stamped in my hippocampus now (they played lot of Supertramp too).  Just remember everybody, “the crux of the biscuit is the apostrophe”.
