Yeah, I think I'm keeping it, even at $20/month. Just haven't figured out my usage scenario(s) yet. My car actually does have bluetooth integration, but I'm cheap enough that I only get 2G/month on the phone, so I'd have to preload all the albums. And when I'm in the mood for something I own, even if it's on one of the iPod classics, I realized I can still listen losslessly through iTunes. Not sure I want to wear out my iPod classics for that, though, so I may start keeping a 1TB with me...hmmm...or maybe a whole laptop, since I'm now getting to the point of taxing the laptop too much...sorry, tl;dr+thinking out loud...
And yeah, I got a 30 day trial, how'd you only get a 7 day trial?
And yes, if I only used it as background music, I'd probably stick with Spotify too (because Pineapple Thief!), but even when I listen at work as backgrond music, I'm listening on good enough headphones that I feel I can hear the difference, so I try to stick with that too, most of the time.
