Here’s Mastercard’s new one. Compared with the horrendous noise that current accompanies the “remove card” message at some places, this is actually quite pleasing to the ear, but not exactly sure if it fits such an old, established business. Which of these corporate audio signatures do you like/hate?

Netflix’s is quite good.

BMW’s is lame. Dislike.

Audi’s is okay, but not great.

And who can forget “chicken parm you taste so good”? But more of a true jingle than a signature/logo.
