Hi, I don't need the ability to play backing tracks (but maybe handy one day), so only really need the lyrics side. I do like the ability to add times in there though, so I can line it up when we are playing the song approximately. I do use Linkesoft Songbook, which is basic, but does the job. I am just evaluating the demo version of this, and I noticed it doesn't seem to recognise bringing in .txt or .pro files (which is what most of my 1400 songs are in). Also, it asks for a Name and artist, which I would have thought it would pick up from the 1st 2 lines?
PDF files seem to come up okay.
Also, another feature that would be good is recognising either Google Drive or OneDrive, given that most people using this subcscribe to MS Office 365 which includes 1TB of backup storage, compared to the 'generous' 5GB that Apple give you on icloud. (However if you pay $120US per year Apple give you 2TB, but at $70US per year, Microsoft give you Office as well as the 1TB).
One advantage that Linkesoft Songbook has it that it has Android and Windows support, which I also use. Since I purchased my Samsung Galaxy Fold 3, I hardly use my iPad.
