I wanted to have a perfect radio app when I'm relaxing on the beach, and I finally got it. It's called Summer Hits. It is full of best internet stations on the web, so I don't have to download anything on my phone. My boyfriend isn't a fan of popular music, he prefers chill out and reggae, but he found a few stations for himself. Categories are interesting, all well planed. When you get tired of the sound of waves, this is good alternative.
