Oddly, most of it is not in English, my native tongue, which allows me to simply enjoy the music, not analyze it. After working out I feel like I've been run over by a truck, so I do not want to waste energy on anything. If there is one philosophy to post-work out (for me), it is to do as little as possible afterwards for at least a day!
Anywho, here are some relaxing songs I enjoy. Aesthetic know-it-alls need not apply.
