SoundCloud

In the SoundCloud app, when you find an awesome song, you can build off of it by creating one killer music station that will give you like-minded songs you might not have ever discovered otherwise. And finding cool new songs and artists isn't the only reason to create a SoundCloud station — it's a great opportunity to set the tone of your workday or your party without ever worrying about the music ending.

It's never fun when you install an app and then proceed to be bombarded with constant notifications. The SoundCloud app, while great in other regards, tends to have a bit of an issue on this front.
