Live music is a ripe market for a new social network!
There's a few music apps, but they focus only on the audio. I wish there were a combined app for managing everything together.
Listening to music (Spotify, YouTube, iTunes), keeping track of what music I've listened to (Last.FM, iTunes play counts), making playlists (Spotify, YouTube, iTunes), organising playlists into folders (iTunes), syncing music to devices offline (iTunes).
I hear about bands I like being on tour (Facebook, band websites, posters), I buy tickets (Ticketmaster, LiveNation, trains), go to events (iCal), take photos (iPhoto), and keep track of the bands I saw live (Excel).
At those events, I buy physical T-shirts, hoodies, posters, and CDs, and get them signed by the band when possible (NFT, Wise, bank cards, cash). I meet other fans while waiting in the queue, and exchange contact details (Contacts, Facebook, WhatsApp, WeChat, LINE, KakaoTalk, iMessage). I then see the other bands that friend likes (Facebook) and check out their music (Spotify, YouTube, iTunes) and the cycle starts again.
When I listen to a song, my mind still makes connections to the memories of that time I crowdsurfed while the band played it on Warped Tour '08 in LA during my exchange programme to California. Having software that could help me create the links to organise all those memories would be wonderful. It doesn't exist yet though, from what I can tell - so I hope someone will write it!
