Since 2012, it's become almost impossible to go a day without hearing some Spotify news.

The online music subscription service--which now boasts more than 24 million active monthly users, with 6 million of them paying customers, according to The Los Angeles Times--is available on iPhone, iPad, Android, and desktop. A web player is still in beta, but is expected to go live this year.

Meanwhile the music subscription wars are heating up. Google announced its own rival service in May, while Twitter launched @TwitterMusic, a discovery iOS app, in April.
