The Google play store is an all app stop for any legal app all over the web. I have been using this service since 5 years. So , these are the pros and cons of this service.
Pros:

Lots of stuff for entertainment
Good quality music
Value for money apps
Unlimited free apps to download
Regular updates for apps.
Easy uninstallation of paid apps
Cons:
Does not load in low speeds
Fails to update external apps
