If you mean for processing, I’m not sure what would be difficult about one credit card processor over another. The 4 major networks do charge different fees to merchants, so if that’s your primary concern, Visa and MasterCard will typically be the cheapest, but that’s more-so up to your clients and what cards they use.

If you mean for purchasing, I would think the only additional expense to you would be any applicable annual fees (which many business cards do have). There are plenty of business-oriented cards that don’t have annual fees tho, like the Amex Blue Business Cash card. If you value customer service over everything, I’ve personally found Chase to have some of the best customer service from a bank/credit card provider, but many major banks will be competitive in that regard.

If you mean more on the front-end / client-facing side, there are numerous services such as Square and Shopify that can simplify and streamline things, but that of course comes at an additional cost.

Hopefully that helps, otherwise if you can provide some more specific info on what you’re looking for, I or others might be able to provide better help/advice.

You should have a playlist already in your library called “Recently Added” and can have Siri or a shortcut play said playlist. I’m not sure how far back that playlist goes compared to what you’re wanting, so if you want to customize it more, you could setup a smart playlist to add all new songs to.

Interesting optic choice. Why not something magnified?
