I recommend you that listen to music in Spanish radios through Internet. You can see the list and the names if you like that. The most famous radios are: los40.es (typical pop radio with all kind languages songs), europafm (I listen this in the car, also with English songs), cadenadial (only Spanish actual songs) and cadena100 (like europafm). The people will recommend you all kind of artist but if you can listen them you can choose better. And then you can download the cd if you can't buy it there ;)
