Not necessarily, if you can manage with your phone then great. However, the very fact that you thought it necessary to post this question might suggest you aren’t 100% sure that is the case. If I were in your situation I would think about getting a computer of some sort just in case you do get asked for something the phone isn’t capable of you’ll be prepared.
I always do this, I email whoever made it to get all the info I can which I then never look at, I also plan extensive modifications that aren't needed and I never get around to anyway!
Oh I couldn’t agree more, I not only ignored country music but I would openly mock it too, until I stopped being an idiot and actually listened to some. Now I’d give up most of the stuff I listened to as a teenager just to listen to Jolene!
I have never listened to Alison Krauss. I particularly like the very close and often dissonant harmonies between Gillian Welch & David Rawlings and the dissonance in the latter’s guitar playing.
