A large digital collection needs storage, so…
iBroadcast has a number of flourishes, too: my favourites are around the sorting by release year with individual tracks, the ability to create playlists from text files (“*track*” “by” “*artist*” works a treat) and reporting the signal path for us digital conversion nerds. The ecosystem is well done indeed, and while it can be an expense (not unreasonable, mind) when I obsolesce one or more hard drive/s it could be a perpetual benefit.
