Best laptops for music production?

Greetings, everyone.
I am looking to pick up a laptop for the sole purpose of managing the background music at my coffee shop—primarily just running some radio streams, MP3s, and similar audio files.
Thank you in advance for your assistance.

Just grab a used T400 or something in that ballpark.
