Thanks guys for the quick replies.
Also thank you for explaining the difference between the two importing methods, that will be very helpful going forward in order to avoid playlist titles containing multiple dates upon multiple imports. Definitely wanted to confirm that before renaming all playlists!
With regard to the resolution, doesn't it depend on how the software handles scaling? In foobar2000 for example, going from 1080p to 1440p on Windows means you're able to fit in more text in the columns, as long as you keep scaling at 100%.
I guess you're saying this strat wouldn't apply to Poweramp and it would be scaled to give the same but sharper image, but I figured I'd explain where I was coming from, just in case that would clear things up.
Thanks again and have a good one
