I recently installed foobar2000 on my tablet running Android M- it crashed on start. It was installed initially in adopted storage so I moved it from adopted storage back onto internal storage and it worked.

So foobar2000 on android has issues with Adopted Storage, Im wondering if foobar2000 will have better support for Adopted storage in the future, since it'll be nice to download my music onto my 32GB microsd, rather than the 12 GB of internal storage.
