TMBG is considered a goof ball band, but there is an underlying maturity and thoughfulness in their lyrics. something that i, again no offense, think you haven't quite achieved in your music. But i think you will. eventually you'll grow independent, get an apartment, meet a girl you wish you didn't, ponder the dynamics in relationships, ponder religion, think about death, life blah blah blah. Not that i don't think you haven't considered this stuff before, but perspective on things changes with experience. and with time you'll establish a way of better articulating yourself. And you can articulate deeper premises with goofball metaphors like TMBG has. Serious doesn't necessarily have to be some sort of whinny venting music (although, you're right there are way too many of these sort of bands around)
writing songs for the sake of writing songs gets old. for example, there's nothing i really feel like writing about, so i won't write because it won't mean anything no matter how many creative puns or metaphors it has or how catchy the song is. Even if other people say they love that song, it wouldn't mean much because the song doesn't mean much. Radiohead does this all the time. Thome york won't play songs that he thinks has lost meaning, even if all his fans love that song. i don't know, i'm babbling, but i hope you get my drift. i only mention this because i see a song from you like every week and i guess it's fine for the sake of messing around and killing some time, but i think you're passionate about music and i hope eventually you take it to be more of an artistic medium than to just make songs for the sake of making songs.
i only mention this to you because you're young, talented and impressionalbe. haha.
