I noticed kids prefer Pandora and Spotify cause it's too much effort to transfer downloaded music to their phone.
I ain't paying for that tho. I use my YouTube playlists since I can listen to it on all my devices. On my iPhone, Music TV will let me download from YouTube for offline use. I use the MixerBox app for online use. On my laptop, I use the Chrome extension Streamus for online use and iTunes for offline.
