Happening here / Tell All

[adantatu2]

Hello guys, I'm trying to organize my music library, but I don't know what to do with these 2 songs:

- Happening here - Is this song a digital single ? Is a gift for the fans in a CD ?

- Tell All - I know this is a commemorative song for her anniversary, but, Is this a digital single ?

And the last question is: Do these songs have official covers ??

Thanks in advance
