You could find the song, album, composer etc, and play the Youtube/s of it. You could also search based on language (e.g. Engish, Indonesia, Chinese) and year introduced, or the genre of song (Praise, Worship, Hymn etc).
It also have a notification to notify you when any feature songs is added to the app, so you would get to checkout what the song that encourages me.
If there's any nice Youtube song you like me to add to my collection, just drop me a note and the link to it.
More enhancement would be made (e.g. ability to save favorite songs, play the youtube song lists etc) if the app is getting traction and blessing many.
Thanks and God Bless!!
