I have had it for about a month now and it's brilliant. It's legal because you don't download the songs you just listen to them, but you can create a playlist so you have all the songs you want to listen in one place. Also the ads come on about every 30 minutes and last about 30 seconds, as chalex said you can pay so you don't have the ads but it's about £9.99 so it’s not worth it.
