I usually listen to whatever is playing on our local radio station Triple J (107.5 FM in Melbourne). I have a number of the Hottest 100 albums they produce which contain a variety of artists. I also grab some free stuff from their Unearthed site which is stuff up-and-coming artists can post their music on and you can download it for free.
For a while I was listening to Milky Chance a fair bit as it was great to chill out to.
I still sometimes listen to my older stuff like Metallica, Pearl Jam, Powderfinger and many other bands that became popular in the 90's and early 00's.
