Extending the life of an older device is a great move, and using them as music players is one of the best ways to do it. The key is to stay away from the app stores and use basic web tools that offer direct file access without any background processes. This way, the old processor only has to handle the audio playback, which it can still do perfectly fine. You should look for a site that has a minimalist design and a very fast search response time to avoid hanging the system. It is a very efficient way to keep your old electronics functional and useful for years to come without spending any money
