You’ll want to search online for a USB hub and find one in your price range with the features you want. I use Newegg for that sort of thing, and I like the Orico brand for it. I don’t have a specific recommendation because I don’t think there is much benefit from one to another.

I will also say that most wireless peripherals are USB 2.0 speeds, so a 3.0 hub would not provide much benefit to them. That said, having more bus speed available should allow for more devices on the hub without throttling each other.

The thing I find more important is an external power source if you’re connecting many devices. I run my mouse, keyboard, webcam, microphone, Bluetooth adapter, controller dongle, and streamdeck all through a hub mounted under the desk.

Generally the person who recorded the music would have a performance copyright on that recording. This is often sold, licensed, or otherwise given to another group to distribute that recording such as through CDs or streaming. That same performance can also frequently be licensed for use in videos, commercials, public displays, etc.

If the campaign purchased a license from the distributor to play the recording at a public event, there really isn’t any consultation with the original artist. Hence, an artist’s music being used for something they do not agree with.

If they did not purchase a license, that’s when the lawyers are unleashed.
