When Apple first announced it was going DRM-free at Macworld 2009, they set up a system where users who previously bought the old, lower quality, copy-protected music could upgrade to the new, higher-quality, non-protected music for $0.30 per single track.
Problem: it was all or nothing. If you had 100 tracks, you had to upgrade every single one of them, all at once, which would set you back $30 (or $300 for 1000 tracks). Now, Macworld (via TUAW) says Apple has seen the light, bowed to pressure, or otherwise fixed the lame, and is allowing users to pick and choose, and upgrade only the music they want on a per track basis.
So, head on over to iTunes to see which of your music tracks [iTunes link] are eligible for upgrade, but make sure you have 1-Click enabled (for now, to avoid some sort of glitch in the system).
Seems like a great step in the right direction for us. Anyone more likely to upgrade now that we don't have all-or-nothing dangling over us?
