Soundcloud or soundcloud player for Garmin forerunner 245 Music?

I would consider adding the Soundcloud API to the options for the SubMusic app. However, according to the Soundcloud terms of use, it is not allowed to cache or download anything for offline use. Therefore it will be unlikely any app can implement this ever. From theTerms of Use - caching:

Caching and Downloading

Your app must not be include file-save functionality, or otherwise designed to cache, download or persistently store any User Content. Your app may employ session-based caching, but only to the extent reasonably necessary for the operation of your app during that session, and any cached content must cease to be available, accessible or playable within your app at the end of that session. If any Uploader changes their settings with respect to any item of User Content (for example, by removing that item of User Content from the platform, or by disabling API access), you must ensure that your app reflects and respects such changes as soon as reasonably possible. Except for session-based caching referred to above, your app must not offer offline access to any User Content including, in the case of audio User Content, as permanent downloads or temporary downloads for offline listening, regardless of whether Uploaders have set that User Content as allowed to be downloaded on the SoundCloud^® platform.

Unless otherwise permitted by applicable law and/or agreed with the relevant user, when a user revokes access to their SoundCloud^® account, you must ensure that all Personal Data and User Content pertaining to that user is deleted from your app, networks, systems and servers as soon as reasonably possible. If you stop using the SoundCloud^® API altogether or if your API access is revoked, you'll need to delete all User Content and Personal Data in the same way.

What about something that ripped soundclouds into a garmin folder for uploading?
