anything that isnt very hard to run should be fine. ive personally ran a distro on an early 2012/2013 mac and it worked just fine. forgot what one but i know it was a very common mainstream one. i also somehow got kali on it so that was interesting too. if you want something easy and simple you should probably use mint or debian if they support imacs, otherwise? its really down to personal pref

for ripping music from Spotify, best solution I know is spotdl which just downloads an album or playlist link given to it, and fetches the equivalent from YouTube.
