Hear me androids

[Talal]

I just got a Galaxy note 2 its my first time using this OS, and there is just too many apps and what not. Can someone tell me which apps i can use for the following purposes.


1) A good pdf reader that lets me annotate them with a stylus.

2) A youtube video to mp3 converter app that downloads the video but converts it to an mp3.

..any other good apps ?

I've googled and looked at the google app store, there was just too much information if anyone has an app that they can recommend it would be great
