Can I add music to iPhone from a computer without my full library? I just got a new MacBook, and I won't be able to restore the files from my previous MacBook (which isn't with me) for a couple of weeks. That older computer has my music library and syncs with my iPhone. In the meantime I'd like to add a couple of albums from my new laptop if possible. Can I add those albums from iTunes without deleting all the music already on my iPhone?
No, the phone can only be synced with one computer over the cable. If you purchase an apple music subscription, your music is cloud-hosted and you have more flexibility.
