I think everyone that has a list that could continue for a just a little while when it comes to music.
Like Abnegation, I grew up listening to Linkin Park. My way was from my family playing it loud whenever they pleased. Because of it I grew up liking them quite a lot and still now frequently listen to Linkin Park. Though most are influenced by sticking to liking a tight genere group type of music, in my house you'd get a suprise after the constant change of music types. Eventually (after my resfusal to believe I would not like music ever) I started to look around for other types of music, finding Paramore and easily liking the band. Though if there wasn't Hayley's extremely wonderful vocals for the band, Paramore wouldn't be as popular as it is.
For some time in between all of this, I had been listening to ATC which was suggested to me by the one and only mother of my family, and started to listen to them more frequently. I also had become a Three Days Grace fan because of my two brother's playing their wrestling game and me saying "Hey, this song is awesome" and eventually started with YouTube to find other songs. I also did this with Sick Puppies this year. After a while my elder sister started to suggest bands for me to go and listen to espically Aly and Aj which at first I didn't really like, but at the time I was sharing bedrooms with her and she kept playing it eventually coming down to me liking them.
This year is the probably the most active year for my music activity as I actually started to try and listen to suggestions that people have given me. Like with Alexithymia~ (my PokeCommunity sister) when she suggested to listen to Amberlin, which I like some of the songs too, not all of them, but they are a pretty good band all the same. I was also told to try and listen to Owl City from my sister which I have gotton into. For the rest of the bands I like I have either stumbled on while on YouTube, aka, Shinedown, 3 Doors Down, and Cascada, or, I have heard at school and have liked then started to listen to them constantly like: Jay Sean, Taylor Swift, and Kelly Clarkson.
I have begun to like some of Kill Hannah songs and Fall Out Boy, though again like with Anberlin, not all of them.
