I used to use the Waking Up app for daily 20 minute guided meditations, and I want to get back into it, but these days I don't use a smartphone most of the time so I'm looking for something similar that I could load up onto the (offline) hardware music player that I use for music and audiobooks. Ideally a number of different similar-length guided meditations (where I could either loop through them in order, or pick one at random for each session). I'm still fairly new to meditation, so I'm probably not aware of all the forms/formats that this kind of thing can take, but the ones I'd been using are 20-30 minutes of mostly silence (but I'm not opposed to the idea of some kind of background white noise) with a guide providing verbal instructions around breathing and relaxation at the beginning, then providing occasional visualization exersizes or affirmations to focus on at occasional intervals.

A few searches shows no shortage of options for this kind of thing (both free and paid), but I'm wondering if anyone has any specific recommendations of something like this that they use or have used and would vouch for the quality. It seems like the kind of category where it would be easy to churn out a bunch of low-effort AI generated slop and disguise it as something else, which I would like to avoid.
