Or Tesseract shaped! Movies about free energy or time travel or space travel or aliens always end up with some sort of tesseract involved so it must be important!
In case it wasn't obvious, I made that last part up.
I've gone back to CDs and purchasing individual songs. Streaming is cheap up front but after a while I found I listen to a lot of the same music usually so its more cost effective for me to buy the music.
Also, streaming music in 5pm traffic doesn't work at all. For me in my town anyway. Spotify just spins. I have a major network and LTE. Maybe its just my area but I find this unacceptable.
We will have solar energy as soon as the utility companies solve one technical problem -- how to run a sunbeam through a meter.
