Agreed, the formula doesn't need to change, however, maybe responses to song requests so that we know if our requests are being ignored or if you just can't get the songs or whatnot.
The one thing about wazee that I would say could use a little improvement would be a little bit of diversification of the alternative genre. While good, there are other styles of music within the alternative genre that are not heard on wazee, but definately keep the formula of mainstream to indie the way it is, I wouldn't trade that for anything. I just feel the station has really stagnated over the last couple years so I have taken to searching out new styles of music (despite coming back to wazee on a somewhat regular basis).
As for the stream, I would be interested it TRYING the alternative bandwidth options but I know that bandwidth for streaming music can be expensive for the broadcaster so if you were to expand the offering of streams, I would maybe bump up to 160 as a trial run to see what, if any, difference there would be.
As for a mobile app, I would be interested in using a mobile app, however it would have to be able to do much more than just stream wazee, android already has many apps that can stream the station. Being able to comment or rate the song through the app and browse the WMD would be key criteria, along with having a built in version of the forum.
Oh, and maybe a few more active mods on the forum to deal with any spam or whatnot.
