PODCASTS.
a podcast is an audio recording posted online, much like a short radio show.

podcasts are benefitial for university students because they contain a short and detailed description on the subject searched for.

In my case, I searched for electric guitar and i found amazing guitar solos and unsigned band music. This let me listen to fresh music from people without record deals and therefore nothing to lose. Also I found reviews on guitar gear and guitars themselves to assist you in what to buy.

podcasts are beneficial because they are purely sound, therefore you can type up work or search for information while listening to the info you obtain from podcasts.
