Artists

You didn t spoil any party .. So on topic ..the word you re lookin for is "Diversity" you see people tend to listen to more genres of music (usualy) , so does the author of this nice colection , so do i .. and others . I'm nobody's "defender " or some prophet but just wanted to say that, (and a point of view), adding pop alongside with Rock, country artists isn t quite strange , on the contrary it shows a diversity in taste .
I personally too listen to Despacito than go to some celtic music , jazz or other things .. (for me it is depending on the mood i am in ). Prolly the author wanted to do this in one single collection and not makin separate ones for each genres of music that he/she likes . And prolly the ideea with the participants that were add here was that those people to complete this collections with artists (if having some , or listening to some ) that match the types of artists and music genre this person based originally his collection .

Either way in conclusion i don t see a big deal in this , and nothing harmful , but on the contrary a nice way for people to comunicate more , and also discover some new artists , music .. etc

Hmm speakin of this .. by the way i seen (in fact i've known of that function ..) there is a button in the personal profile "Favorites" and when one person hits that it shows its fav artists alongside with the fav songs added to that list .. NOw the thing is..can t there be add a separate one for not mixing those two sections !? Like next to that a button alike "Favorites Artists" . i'd kinda see it useful for one individual to not have them mixed

Hispanic is the word I believe you're looking for.
Latin and Latino are a bit different, but for Luis Fonsi, they would both apply.

(You're right. I would not use "Spanish", except to say "Spanish-language".)
