I'm sure she wants to play modern music. We find lots of videos on youtube of people playing modern stuff with a double bass/bow. I understand that playing by ear is best, but she is still learning to play in general. Only one year under her belt. I'll try the music stores in town.
Trust me, as an extremely experienced EB player with literally hundreds of covers of classic rock, blues, 90s pop/alternative/grunge/, '00 pop, etc. all transcribed by ear under my belt....there is a LOT of easy, almost trivial stuff out there. The genre(s) is just nowhere near as complex as jazz stuff and most classical, in general. Off the top of my head, some suggestions for her to get her feet wet that are easy and popular. This list is seriously pared down because I could go on and on with four chord songs.
Beverly Hills - Weezer
Float On - Modest Mouse
Howlin' For You - Black Keys
War Pigs - Black Sabbath (probably the most complex in this list but very fun)
25 or 6 to 4 - Chicago
Sunshine of Your Love - Cream
Bad Moon Rising - CCR
Sweet Home Alabama - Lynryd Skynyrd
Horse With No Name - America (Seriously, three notes)
Break On Through - Doors
Any friggen AC/DC song
Desire - U2
Gold Dust Woman - Fleetwood Mac - has a cool chorus of non-roots.
Blister in the Sun - Violent Femmes - do yourself a favor and never listen to anything else by this band
Blitzkrieg Bop - Ramones
American Idiot - Greenday - a hook and a couple chords
What's Up - Four Non Blondes - three chords
What I Got - Sublime - two
Hey Jealousy - Gin Blossoms - four on this one
and on and on and on.
