Test card music for the Museum

[ppppenguin]

One missing feature at the Vintage Wireless Museum is music to accompany the test cards. To do this we need a small music player which we would load with suitable music and left playing on an endless loop. I have no experience of this sort of thing so do you think either of these would suit?

Or maybe somebody has something lying around that they would donate.

Important factors for the Museum are:

It must run from an external power supply. I have loads of wallwarts of assorted types.

The audio output must be able to feed a line level input rather than headphones. Presumably this isn't a problem, just preset the volume and let it run.
