There's an internet radio called Radio Paradise that I got into a while back, that has introduced me to a ton of awesome music I had never heard of. I absolutely love music (especially live), but lost touch with keeping up, while raising kids etc... Anyhow, this station has an app for my phone as well, it's free, and has a great option where I can rate the songs I love and later upload for offline. Hard to describe the experience, just try it if youre looking to expand your horizons. There are also genre options, but the main mix is fine imo.
