Torrents.. cd quality no ads ever..
The whole point of software like Spotify is to be able to stream music WITHOUT downloading it.
So there's that...
But you'd already know the songs you like.. therefore you can pre queue a collection of them, enough to greatly exceed consumption during time periods in the car..
Now.. You can also setup a webserver to link to your fone. even 3g is fast enough for flac..
Spotify may have a larger collection upfront.. but you'd have to fiddle with the dial anyway to find the stuff you like...
so you would've had to created a play / fav list in the first place.. (On spotify)
Torrenting, wouldn't be a significant increase in effort relative to organizing such a list on spotify. so yea..
torrenting.. better quality, arrrrg discount,
