EMOJI USAGE & HIGHLIGHTS

Hi, got this question :

is there a possibility to Highlight specifics songs in the same playlist?
I have this problem : I want to highlight 200/300 in a list of 2000, because I have to sing 3,4 hours but I don't know now what will be ok for a specific moment, and I don't want to spend too much time scrolling through 2000 songs while I'm singing. I know there is the 'playlist mode' but it's too tricky for me because I'd have to divide songs in 5/6 groups (=playlists) and it become difficult to manage all those folders during a performance.
I thought to do this : to ASSIGN different colors/emoji to every song depending on the 'kind' of song. So it will be faster for me to decide watching the color (or the emoji).
I've seen there's is the Emoji but I cannot find out HOW to assign it to a song.
pleeeease help me
Thank you

Perhaps filtering you songs with some keywords?

Hi! Thanks for your suggestion, bit i really can't find differences between filtering and using a playlist.
Ven with filters i'd have to look for the song going into a folder and scrolling, wouldn't I?
What does the emoji exist for exactly?
Thank you
