if you haven't checked out Sigur Ròs, absolutely give them a try. They're an Icelandic band--many of their songs are purely instrumental though. I'd recommend their songs: Fjögur Píanó, Valtari, Untitled #3, and their album "með suð í eyrum við spilum endalaust". really atmospheric stuff.
Just discovered this guy recently! Great music and seemingly a great personality. If you haven't heard his song 'Late July' you should definitely give it a try, its a great story.
For those of you into electronic music, check out ExMag's new album, Proportions.. solid gold, here's a link: https://soundcloud.com/exm4g/sets/proportions Other than that I've just been making my way (slowly) through my jazz collection: Miles, Brubeck, Metheny, others. Here's a favorite from that list: https://www.youtube.com/watch?v=loHQdupqcFY
I would think that smartphones would be easier to get away with than not! Many people modify their laptop/pc internals as well as dig deeper into the OS and source code, giving them a greater opportunity to see something they're not supposed to. Think of how many times someone--even a tech savvy person--has cracked open their smartphone?
