My sister introduced me to this handy lil' guy earlier this summer.
you can play virtually any song ever from all over the world. There's only 1 I haven't been able to find and that was from an unsigned band so I guess it makes sense. If you're looking to hear a song without downloading this is the best way. Sometimes the search mechanism can be picky, and it won't fix your spelling errors so you have to know what you're looking for but I've used it so much this summer and maybe it will be useful for you too!
