Maybe things are different in other parts of the country
Don't think so
Whilst I agree fully with Maria, and it sometimes annoys me greatly if people assume that pop-singing equals "easy", my experiences are much in line with what Brynfan has written. Many, albeit not all, students who exclusively sing pop and are not open to try new things apart from the repertoire they have set their mind on, don't last long. They tend to think that since everybody is somehow born with a voice, a few lessons will do, and they are rather shocked when they find out that their vocal problems don't magically disappear over night if they don't put the work in. Most of these people come to lessons fortnightly at the most and do no work inbetween, and then they wonder why there's no improvement. And yes, sadly this is much more common amongst pop-singers.
Having said that, this doesn't mean that I don't have some amazingly talented pop- and rocksingers who really work hard. However, the overall trend is sadly like I mentioned, and I have my own theories as to why, but that's not the subject.
Seer_Green, I very much use a "give and take" policy in my lessons, which means for every song I pick, I also let them choose one. It often means I need to transpose it etc, but I don't mind. It keeps them focussed if they do something they enjoy, and almost any popsong can be altered in a way that it is suitable even for adolescents. Only very rearely did I have to say that a song was not suitable because they were copying an adult voice too much - this problem usually disappears if you transpose or alter the song and they can't use the same vocal patterns anymore.
Did you ever try the Rockschool Vocals-series? They do 3 volumes (Grades 1-3, 4-5 and 6-8) for both female and male vocals. Many of the songs come in two keys, the accompaniment CDs are of good quality, and they also contain "pop" theory and aural (you can also get a companion guide for this). Since Rockschool is essentially a daughter of Trinity, the series is put together well, and you will find repertoire even for younger singers.
I know you normally don't do pop and rock, but I think these volumes might be worth having, if you didn't already get them in the past.
Edit: Sorry for the typos, I think I'm not fully awake yet. Hope I found most of them
