Bandcamp is one of the best places to find affordable DRM-free digital copies of a band's music. And when you guy physical, you also get immediate digital downloads.
But if your favorites aren't there, the iTunes store is a surprisingly good alternative.
Songs there are still DRM-free, and they're still 99 cents US.
@killyourfm Yeah, but you only get lossy music files, if you buy it on Bandcamp, Tidal or Qobuz its lossless so I buy it there if possible
