At a $120/year for 6 years, you've basically spent $720. That is amazing. I, on the other, have spent $0 on all music in my entire life (excluding concerts).
That wouldn't have given access to as diverse music as Spotify does, of course. But on average, how diverse is the music taste of random people?
I don't necessarily see this as sad. I spend money on lots of things that have no lasting value (beyond memories), many of which are experiences. I think we over-estimate how much time we have in ours lives anyway to enjoy these "permanent" things (like CDs).
How will you read the sleeve notes and who did a rubbish job of mastering and mixing this album?
I'm in the midst of cleaning out our basement filled with old cassettes, VHS' and CDs. My siblings who moved out years ago, asked me to donate them or throw them away. So now I've got to spend hours sifting through piles of media to figure out what to do with them.
It's such a hassle. (Yes, First World Problem)
My parents as Costco users have this belief where having physical things, especially in bulk, is a key strategy in savings. They hate subscription models especially for digital formats. But what they fail to acknowledge is space is valuable too. The space lost around the house because of their buying habits and unwillingness to let things go (items that were bought on sale but never used, old clothes, magazines, books, media, etc.) is pretty sad.
My parents have the problem of hoarding things and they refuse to sort anything out, so it'll be a MASSIVE pain if/when anything happens to them and I have to sort it out. I will need to just have a bonfire or burn the house down or something.
Spotify fills my use case almost perfectly.
For me the lasting value of experiencing music in an efficient and uncluttered way far outweighs that of physical media.
If you think of the time spent to find and buy 720 songs, at just one minute each, that's 12 hours spent just buying songs. The value of spotify is wasting no time or money on acquiring or managing a music library.
I'm paying spotify to provide me a service to access music. Now I don't need to hoard it and waste my OCD on endlessly minding 'my' collection.
For me the lack of any physical items or files that I would need to administrate is a win.
I don't care for physical media either but I buy everything I like as digital lossless audio. Not owning my music wouldn't work for me. Not that it has to be like this for everyone, it's just something to be aware of.
People have different budgets but 120$ a year is not so much to pay for a thing that provides some noticeable value for me.
Spotify is a similar service that provides me something I want at a moments notice.
(Assuming you're listening to music at all because otherwise why go to concerts...)
