I buy digital music because there is no more space to keep CDs anymore.
Also, many digital version is HiRes version, sounds better I think.
And some new score has only digital version, so I have no chose.
But I still buy CDs if they are very special, or box set.
Because they looks awesome.
For example, I buy both digital and CD of Godzilla VS Kong, because it has HiRes version, and the CD looks great together with all the others Godzilla's CD.
But I only buy HiRes version of Wonder Woman and Dune, not only because sounds better, but also the CD version is actually CDRs.
