Recently my girlfriend and I have changed the alarm sound, it is important to wake up with a smooth sound rather than "ALERT, ALERT".

It's important to be relaxed in any activity that you are doing and for what I see this app has a lot of good options. I read some weeks ago that listening to videogame music is a great way to complete tasks (studying, working). After all, that kind of music is designed with that purpose.

Thank you for your recommendation, I'm going to check out this app.
