That depends on why do you need to learn spanish.

If it is just to have regular conversations you could start to listen music, specially from mexican artist because the have a very light accent, but not traditional or folk music, at the beginning romantic or slow pop, then to pop and rock.

Some artist you could listen are:
Fernando Delgadillo
Edgar Oscerasky
Benny Ibarra De Llano
OV7 also knowed as Onda Vaselina (already dissolute)
Kabah (already dissolute, both OV7 and KABAH were pretty commercial music but good to learn bcz you can hear different voices and learn to pronounce)
Emmanuel
Yuri
RBD (not my favorite, totally bubble gum)
Kany Garcia (not mexican)
Miguel Bosé(not mexican but spanish)

But If what you need is learn to have bussines conversations you really need to get a course in some school or institute because in spanish there like 7 ways to name one thing and sometimes you learn to talk in slang that may not sound like slang for you but is not the right way to speak is you are making bussines and want to prove you prepare and reliable.
