Download songs in album named folder insted of songs

[imashwani]

As of now the songs are downloaded in folder names as "songs", just want to add feature of downloading the songs in the folder named as whatever if the name of the album.

For example:
https://www.jiosaavn.com/album/kalank/Jv-F,nN0JoY_
the above album name is "Kalank", so just change the name of folder from "songs" to "Kalank"

Album name would be great for downloading songs in different folder according to Album.
