Quoted from lpeters82:I still buy used CDs. For me it's the cheapest way of legally owning the music.
Now there are services like Apple Music where you can pay $10/mo and download any song right to your hard drive. No physical media to junk up the house and you legally own the songs you want. You don't even have to get the whole album. It's up for debate whether or not that's a good thing.
