I listen to a lot of youtube and mp3's collected over the years. Mostly covers done acapella, multitracking or looping. My tastes are older but I like some of the modern stuff as well. The musicians must be good since I have near perfect pitch; it was hell for me when my sister, son and daughter learned new instruments. My son is in the Ottawa Samba group -- latin drumming. My wife is in the Ottawa Harmonia Choir. My daughter has a bachelor of music in flute. There are 2 pianos kicking around, an alto sax, a violin, flute, a baritone sax, drums, my grandparents piccolo. Yeah, lots of music of many different styles.
Looping:
http://www.youtube.com/watch?v=6u988iJlkZQ cello -- don't like his techno band stuff though
https://www.youtube.com/watch?v=WhBoR_tgXCI -- dubfx
https://www.youtube.com/watch?v=MER_pqH8opE -- pagagnini looping violin, also funny
https://www.youtube.com/watch?v=UXWcP21nBzg -- like her energy, but I don't watch the video -- distracting
https://www.youtube.com/watch?v=9f2X34PYKQw -- a new one I found on the voice
Instrumental -- generally so I can work while listening:
https://www.youtube.com/user/ThePianoGuys -- just went to their concert in Ottawa
https://www.youtube.com/user/AndanteLargo -- quiet classical guitar
https://www.youtube.com/user/Gabriella9797 -- another guitar
https://www.youtube.com/watch?v=yflWG-e38OU -- LAGQ loose canon
Vocal with instruments:
https://www.youtube.com/user/KurtHugoSchneider -- like Kurt and Max singing more than Sam
https://www.youtube.com/user/natalydawn -- I like a lot of hers -- but my wife can't stand her -- acquired taste
https://www.youtube.com/user/walkofftheearth -- went to the concert in Ottawa last year
https://www.youtube.com/user/OkGo -- love their videos
Acapella -- especially with good bass singers:
https://www.youtube.com/user/PTXofficial -- Avi and Kevin are both great
https://www.youtube.com/watch?v=Gerr99h0nS8 -- Club for Five -- listen to the bass
https://www.youtube.com/user/HomeFreeVocalBand -- not a country fan but these guys are great
https://www.youtube.com/watch?v=0l3dsHCScxU -- then the bass from PTXofficial sings with HomeFree
