There's way more to a music streaming service than just a silly theme.
For starters, all my home receivers and BluRay players support Spotify out the box which means I have my music wherever and whenever I want. At work I can do the same if I desire through a web browser.
I switched from spotify to apple music. i used a tool to move my playlist between those services. Was MusConv, pretty fast and easy to use. it's perfect for you if you want to keep all your music information in both music streaming services.
