there is this website called pandora.com it lets you listen to music free. But, its more than that. It askes you your favorite band or song and it works to find related songs and bands and in the end acts as your own pesonal radio station, only playing music you like (or introducing music you will proabably like) all for free.
Check it out!
As a side, note, I typed in switchfoot as my favorite and the first song it pulls up to represent the overall style of switchfoot….”Life & Love & Why” nice.
