Especially when they play the Lead Guitar in a Garage Band!
Jeremy Johnson of Phineas and Ferb Franchise, a Nice Guy who many girls seem to like(Especially Candace Flynn-Fletcher), plays in a band named "Jeremy and the Incidentals", and I could go on but I don't really feel like it right now.
Flash Sentry of the My Little Pony: Friendship is Magic/Equestria Girls Franchise, a Nice Guy who is well liked by others at Canterlot High plays in a band named "Flash Drive", and despite being Sunset Shimmer's EX-Boyfriend he still remains a Close Friend to both her and the Human Mane 6.
Some of you out there my believe that Jeremy is better than Flash, but to be fair Jeremy had a 4 Season Long Series with over 200 Episodes to get a bunch of chances to get character development in spite of the main focus of the series being about the antics of Phineas, Ferb, Candace & their Friends doing something while Perry the Platypus/Agent P fought against Dr. Doofenshmirtz, where as the writers of the Equestria Girls Franchise have barely even scratch the surface of developing Flash Sentry's Character.
So far Flash has been seen as more like an "Accessory" than a Character in the eyes of Many, but honestly the Main reason why Jeremy Johnson was created was to be a Love Interest for Candace in the P+F Series, much like how the Main reason Flash Sentry was created was to be a Love Interest for Princess Twilight Sparkle in the First EQG Movie, so truthfully Jeremy Johnson may be seen as an "Accessory" as well.
And despite Candace being obsessively in love with Jeremy, she did at least once show that she wasn't 100% Loyal to him, namely in that one P+F Episode entitled "A Hard Day's Knight", where she instantly developed a crush on a British Noble who resembled Jeremy in England named Charles Pipping IV, so Candace has had a crush on 2 Identical looking boys in 2 different countries, much like how Pony Twilight has shown interest in both the Human & Pony variations of the same guy in 2 alternate dimensions.
Anyways let me know how all of you feel about this pair of Guitar Playing Nice Guys in the comment section below.
