Welcom to steemit there are tons of oppurtunities and platforms to pursue music and gaming here on steemit. For music there is Dsound which is like the Steem version of soundcloud. We also have DTube which is like youtube and we have Dlive which is like twitch. I myself am a gamer and a tech person and Steem has been a fantastic platform for me to create my content on. Steem on and good luck
